First-hand Account Of The Leonid Shower 39

chongo writes: "The Leonid meteor shower certainly lived up to its hype this year. At Fremont Peak, CA (USA) we saw a peak rate of 2408 meteors/hour. We saw many bright fireballs. During the peak (18 Nov 2001 1015-1130 UTC) there were frequent instances where multiple meteors were visible. Because of this, we suspect the true rate was likely higher than 2500/hr." We've also heard from several folks who were foiled by weather, but it's good that at least some people got the full show. Update: 11/18 17:09 GMT by T : BrianGa writes: "If you missed the show, like I did, you can see some still pictures and animated pictures." He also points to a site with a preliminary graph of the number of meteors visible on November 18th.

  • Here in the Seattle are we got up to around 1/min then the 10:00-11:00 UTC time frame. Some estimates predicted a later, larger peak around 13:00 UTC but it was cold, and we were very tired. (We were up then because most of the predictions I found on the web showed the peak then for this area. The universe in it's typical perversity seems to have chosen the lone outlier as the correct prediction.)

    Most of those we did see were near the zenith and left fairly long (10 degrees), spectacular trails. Based on what I've read elsewhere this was probably the leading edge of the storm. Even missing the peak, it was beautiful and worth the cold and the wait.

    I watched the sky this morning from my backyard in the suburbs of Cleveland, Ohio, where I suppose there is moderate light pollution. Fortunately the sky was perfectly clear. In my first outing, between 7:15-7:45 UTC, I observed a total of 10 meteors in that half hour. I later returned for what was supposed to be peak time around here and watched for 50 minutes from 10:00-10:50 UTC. During that time, I observed 220 meteors. There were quite a few very bright fireballs, and at several times I observed two or three meteors flying across the sky at the same time.
    • Out here in Vancouver, WA we were able to see a pretty impressive show. It was clear save for a moderate sized cirrus cloud that passed over the course of our time out there. But that cloud did nothing to obscure even a lot of the smaller ones. Alas, I did not keep close track, but there were probably close to an average of 1/sec for the roughly two hours we were out there ending roughly 2AM PST.. 'course due the lights of Portland lighting conditions could've better. But hey, I'm not complaining. It was still quite a show.

    Actually Wellesley Massachusetts USA, bedroom suburb about 15 minutes/miles outside Boston. With moderate glow from the city, nearby parking lots, and a streetlight 30 feet away. The horizon was entirely obscured by surounding houses & trees. From five to six am EST.

    Impressive

    Oftentimes multiple tracks visible at once. Very "bursty" activity with gaps of 5 - 30 seconds between sightings, then often several together or in the same part of the sky separated by moments. About one really bright one a minute.

    Paths were often at angles to the horizon, once or twice almost oblique. The paths themselves were also often quite prominant being very bright themselves and lasting up to a few degrees behind the meteorite and lingering for a second or two in some cases.

    The most astonishing thing was if one laid back as so that the zenith was centered and nothing but sky was in the field of vision there was an almost constant sparkle of *something*. I've done and taught astronomy before but I've never sen this much activity at once - even from this relatively crappy location it was obvious something dramatic was going on overhead.

    I'll not attempt to offer counts or speculate on the rate as I was in a lousy location, they're hard estimates to make accurately and frankly I didn't care. It was a deeply impressive sight and I'm thrilled to have witnessed it. In a single hour of viewing I likely saw as many meteorites as I've seen in my life before, never so many multiples at once.

    At one point it was like popcorn popping: "Look there... Oh!.. Oh!.. Down!.. Over!.. Uhhhhhhh THERE!"

    • I probably had the worst spot in the US for the event. Right across the Hudson from Ground Zero, NYC. They're still working all night so as bad as NY is, it's all the worse with the amount of light they're giving off at that location.

      It was still spectacular tho. At about 1am, I saw a couple of spectacular fireballs close to the horizon. A couple of little ones here and there. Went back out from 4:30 to 5:30 and there was at least 1-2 a minute visible, and bursts of up to 10-15 per minute. I really was beautiful. Smoke trails were clearly visible for the larger ones. We even saw one that left no trail really, but seemed to be just a greenish explosion in the middle of the sky. Amazing.

      I'll definately be renting a car and going upstate for the next big shower that comes along.

    I opened up our observatory at CU for my lab section (and any others who came by). I was worried that they'd be disappointed after the hype, but everyone who came seem truly glad to have gotten/stayed up for the event. Either I have a particularly good group this term (which is at least partially true) or it was a pretty impressive even.

    I can't begin to estimate the peak rate, as I was jumping between staring at the sky and moving telescopes to various planets and nebulae. But when I had time to look east at Leo, I could see at least one meteor ever few seconds (which correspords to at least 1000/hour). Oddly, while the number of meteors/per time was highest to the east, near the radiant, the quality of the meteors was best looking near zeinth or even westward. Many of the meteors in that section of the sky were brighter, bigger and left trails that persisted for tens of seconds. That, and the mountains made a splendid background.

    I had one vistor claim to have seen color in a particularly bright meteor, but I was looking in the opposite direction at the time. Which brings up the old lightening-spotting effect: whenever someone says, "Oooh, pretty one!" everyone else looks in that direction, despite it being too late. There is some sort of poor conditioning going on there, but I'll leave that to psychologists.

    In any event, if you didn't see these you either were unlucky or you should have gotten up for this. Either way, be ready for next time!
    • The show was about the same, if not even better, out on the CU (Cornell University) golf course. It peaked at around 5 AM, with a spurt of 4 or 5 meteors every 15-30 seconds. Every 5-10 was a very bright one leaving a trail that persisted for at least 2-3 seconds, and I personally saw 4 fireballs.

      Unfortunately, many other people had the idea to come out on the golf course, so there was an excess of idiot noise, as well as several pricks playing with their flashlights. Still, the show was very impressive, especially considering that during my entire life I've seen no more than two other meteors before tonight...

      I saw a few with color-- at least one was bright green and there were a few that were green-yellow and some that appeared to be redish. I don't know how much of this was an afterglow artifact and how much of it was real, but it looked stunning. :)

      My vantage point was Kerr Lake, NC. I went camping with some friends and we took a home-made dobsonian telescope to stargaze with prior to the shower. The conditions were about perfect. The sky was clear, there was very little light pollution, it was dry, windless, and actually pretty warm for mid-November.

      I dont really know how to gauge the rate, but at the peak (5:30-ish EST?) I was seeing meteors about once every second with bursts of 6-7. It was hard to catch them all as they would appear in nearly every quadrant of the sky. After about the first few minutes I had already seen more meteors than I had seen in my entire life previously, so it was well worth the trip. :)

      • I definitely agree... I was in my back yard on the east side of Raleigh (fairly close to you). The night could not have been more perfect (well, a little warmer, but I'm not complaining). I saw one meteor streaking toward Orion that definitely was bright red. Most of the colors I saw were greenish blue, though. I'll never forget one fireball that pierced Orion about mid-chest and exploded near the middle!

    • I stayed out for about two hours and watched (in southeast Denver - limiting mag about 5) and some of the brighter meteors were definitely colored. The majority were white (whether because they really were white or because they were too faint to detect color in), but some of the brighter ones were definitely greenish or bluish in color. Also, a nucleus was visible at the head of a few of the meteors which was usually orange, but sometimes yellow. In any event, I should be able to verify colors through some of the color photos I took. I was going to get them developed today, but I only had time to go to one place and their developing machine was out of order. So tomorrow night I'll be scanning negatives and seeing how much color they show.

    I was up at 4:30 (AST); nothing much happened. At 5:00, the show started; between 5 and 5:15, the sky was nearly cloudless and the display was quite impressive - a meteor every five seconds or so, with multiple meteors several times (once, a short & quick one shot out below the radient; as it did so, a similar one shot out above the radient. Very keen.). Quite a few fireballs, as well (at least three observed). Clouds began obstructing the view at around 5:15, and by 5:30, only patches of the sky were visible, though every once in a while you could see a meteor from behind the cloud cover, which in some ways was more interesting than the meteors themselves. All in all, a great show: some of the fireballs were amazing, and the consistency after 5am was great.

    This meteor shower just rocked! I went up into the hills at Henry Coe State Park near Morgan Hill, CA to escape the skyglow, and the show was just incredible. I can't even estimate how many I saw (hundreds?), but at the peak they seemed to be coming down like a light rain (a meteor "shower", if you will). Many fireballs died with a bright flash and left a trail that lasted for 10 or 15 seconds.

    What was especially fun was that it was so dark in the hills you couldn't tell if anyone else was there, until a fireball streaked across the sky and a hundred voices from the mountain said "oooooooh".
  • I was all hyped to stay up for the show last night, but I was also trying to write an 8 page research paper that's due on Tuesday. At about 4:30AM EST, I collapsed on my desk from exhaustion and my friends didn't wake me up until after they came back in... damn work...

    I'm down in Palm Beach County, and went out on 441 out towards Okeechobee, out past Moroso to a little side spot I knew and have used several times for stargazing (Milkyway very visible). Halfway there, I had to pull over and just watch for a few minutes - I was getting too distracted by the streaks I could see out my window.

    All in all, an incredible experience, it was cloudy only to the east (sometimes lit from behind), so there were tons of long streaks visible (at the same time, different colors, different speeds and different entry angles (not straight out from a central point)). I saw no exploding or splitting bolides, but lots of very persistant dust trails - as the sun was about to rise, they all lit up, and the sky was crisscrossed with them. It was very subtle, but really really nice.

    I dragged my girlfriend out of bed at 4 am and we took a tarp and sleeping bag to Prospect Park, where we had a nice view in a wide-open meadow near one of the highest points in Brooklyn. Pretty much nothing but sky. There were streetlights, but they were pretty far away and weren't a big problem. Incidentally, there were quite a few other people out there.

    I've only seen meteors twice before, and they were nothing like this. It was quite a show. We saw quite a few of the big ones that left a "snail-trail" that could be seen even if you missed the initial flash. There were several multiples, too.

  • Went out into the Everglades at 3:00 AM, to meet my photo-geek buddies who had cameras mounted on star tracking systems, etc...

    They had a strict no-light policy while running exposures, so you would hear "OK, apertures open", and "apertures closed". (lol)

    At first I was disappointed, because it didn't seem any better than last year, but then we started getting bursts of activity, I think at one time I saw as many as 4 or 5 trails in the sky at once, and that was just looking at one quadrant.

    The coolest thing was seeing trails that didn't disappear for up to a minute or two, until they started losing shape, drifting in the wind. (wind was almost nil, which was great for photography)

    We found it didn't matter which way we pointed cameras, because any direction you looked, you were bound to see one in a few seconds.

    I believe I saw at least one meteorite that burst into multiple pieces, before winking out.

    We kept on seeing this level of activity until the sun started to rise. From listening to my friends, and my own sightings, it seemed one of us saw something every 2 or 3 seconds, on average.

    Even though I have never seen this kind of volume before, they were all small. Didn't see one that fell all the way to earth. (Back in '91 in Canada, I saw one that broke up in several pieces and fell all the way down behind an island)
  • I had my alarm set for 3:30am PST, but then yanked it back to 2:30am PST, after a news report saying that would be when it started to peak. I woke excited, I got up and went outside for 30 minutes. Not a fuckin' thing. It was lightly cloudy, but you could see stars in the sky.
  • I stepped outside on my friend's balcony at about 3:30 CST and saw two inside the city limits of a small city through a good deal of light pollution. My friend came out and counted six. We dressed up and rode north out of town. Starting from 3:48 CST until 4:30 CST we counted 520. We stopped counting then, and were treated to probably about 300 more.

    Right before we left at 5:00 CST, we both looked over at the constellation Orion. One came in from over the top of his back shoulder and right above the first star of his belt, it split into about 4 pieces. That one made our night, seeing Orion getting a shot in the gut. Also, several times, we would be facing north, and then a bright flash would be in the south, bright enough to have us swing around real fast. It was quite amazing.
  • I was watching about an hour outside Charleston SC with a few astro profs and other students from one of the local colleges. Fantastic show. Started off with some meteors from Taurus, then around 1 EST, saw some spectacular earthgrazers. Long bright green trails that stretched across half the sky. At the peak, I was easily seeing meteors every few seconds, and sometimes 3 or 4 at once. As someone else said, most of the more spectacular ones were seen at zenith or towards the horizon rather than from the radiant. This will be one show I'll remember for quite some time.

    Jupiter and the Andromeda galaxy also provided some nice viewing while we were waiting for the main show to start.
  • Lousy weather ruined it for me. We had several clear nights all week long... and then Friday comes along, and friday night it get's cloudy and starts to rain. Saturday came and went and it kept cloudy all day long. I even stayed up 'til 5 AM, hoping to catch at least a break in the cloud cover for a few minutes (and reading Slashdot all night long, to pass the time). Nada.

    Back in... '98, I think, the weather was great, and me and several friends drove out to a ranch an hour away from Monterrey, and we saw a great show, too. Nothing like this one, I imagine, but still it was pretty cool. I think we saw about 100 meteors / hour, some with beautiful colorful trails that lasted for several seconds (including one with a green trail that lasted almost a full minute).

    Well, I hope I'll be able to see it next time around, which'll be about... 2040 or somewhen close. Soudns like a great thing to do with any future grandchildren I may (or may not) have.

  • I saw the whole thing last night, from about 2 AM to dawn, on the side of a mountain above Apia on the island of Upolu in Samoa. It was absolutely perfect, apart from a faint sky-glow from downhill. My mother, my little brother and I took lawn chairs, blankets and mozzie repellent, and settled down.

    I saw the first meteor while getting out of the car. It was simply stunning, a long streak of light with a glowing trail. It was one of the best I'd ever seen. Little did I know then that I would see over two thousand of them in the next three hours.
    In fact, we would have seen more if we had been able to watch both halves of the sky at once.

    It was easy to see the meteors radiating outward from Leo, and the sense of scale that gave me was simply amazing.

    The best one we saw was intensely bright, brighter than Venus at its brightest, red, and right overhead. Bits were literally exploding off it as we watched. It traversed at least an eighth of the sky before exploding, leaving a quickly-fading orange trail and a slow-fading green plasma cloud.

    It certainly made up for the 1998 Leonids, which were obscured by a gargantuan thunderstorm for me near Canberra. Although the fact that I was ensconced in the back of my station wagon, on a mattress, under a sleeping bag, with my girlfriend did make it easier to pass the time.
  • I took a group of about 30 or so students to the local observatory of the Lehigh Valley Amatuer Astronomy Society [lvaas.org]. We had a couple of our members there to help me out openining up the various domes and manning a couple of portable telescopes. They had set up some outdoor loudspeakers playing "music to observe by" and heated up the coffee and the hot water.

    We started about observing about 2 AM EST - and in between seeing the sights of the sky we were counting something on the order of about 50-70 Leonids per hour.

    At 3:45 AM things started to get truly lovely, so we set ourselves up in the lawn chairs and started counting rates for a minute at a time every 5 minutes or so. Viewing was okay - given the relatively urban setting - with seeing down to about 4.5 Mag and calm atmosphere and high humidity. We counted rates increasing from around 2-3 a minute to about 14 a minute getting close to 4:30 AM.

    At 4:45 AM we had high clouds start to scud across the sky, and I gave up formal counting since there would be no normalize the numbers. At our peak around 5:30 AM or so, we were seeing a couple of bright Leonids a minute, some so bright that they lit up the domes like a lightning flash, as well as many (~.25-.5/second) smaller Leonids. We saw a number of truly lovely simultaneous events. The best part was that two or three atmospheric skipping meteors were seen as well.

    People from the surrounding area started joining us about 4 AM and we probably had something like 70 people or so up there just before dawn. It was like watching the fireworks on the Mall in DC on the 4th of July with people Ooohing and Ahhhing, and occasionally cheering. My students fanned out in the crowd and I heard them explaining what we were seeing to the new arrivals, and showing them around the sky.

    We didn't get to see the full effect of the storm because of the high clouds, but the spectacular fireballs, and the mood of the crowd made in a once in a lifetime event for me. Truly superb!
  • In the city... too many lights. As we drove out of the city, the fog got thicker. and thicker. and thicker. You could literally stand 20 yards from your friends and not see them. However, fog generally allows you to see straigh up, so I did see a few (24), including 3 or 4 doozies (meaning, they were really bright.) It was actually a pretty cool experience, because it was fun *and* spooky.

    On a side note, any train running near you in a fog sounds like it's coming *right for you*
  • Sunday evening, myself and gf drove up to my parent's small (60 acre) property specifically for this. Dad woke us up at 3:20 CST, and we sat outside on swags with hot cocoa for the next hour and a half getting stiff necks.

    This was definitely something I'm glad I saw. Other people have written great descriptions of what the shower looked like, but nothing compared to the feeling of actually being there, watching the sky being traced with trails of light. One really impressively bright meteorite left a trail that persisted for almost half a minute!

    My Grandfather was there too, and he'd seen the 1933 show - which he thought had been better, but then he didn't stay for long (cold!!).

    The predicted peaks were sort of noticable, in that there was a definite increase and then gradual decrease in the number coming in, but there really wasn't more than a minute in the whole time where none were visible.

    My dad took a few long exposure photos, which will be a nice reminder. If you missed it this time, make sure you're in a good spot in 2034 for the next really good show - it's well worth it...

    I think I'll be trying for the Nullarbor Plains, myself.
  • Peaked at about 1400 per hour from Thorofare Mtn Overlook (3,600 feet) on Skyline Drive in Shenandoah National Park (about 90 miles west, southwest from Washington, DC) around 4:30 EST. Clouds/fog about 1000 feet below did a good job of blocking the light pollution from below, perhaps adding a quarter to half limiting magnitude to the skies.

    Long and bright, short and bright, dim and short, exploding flashers, point source flashers, long ones that changed brightness as they skipped along, it was quite the show. Beat the 1998 show by quite a bit, if not because it lasted for four+ hours instead of the 45 minute tease we got in '98. Still not 100,000 per hour, though [:-)]

    Before the main part of the show started, showed about 50 people M-42 and Saturn through my 20-inch dobsonian [ladyandtramp.com], many of which had never looked through a telescope before. Had spent the hours between 10pm and 2am chasing down some faint galaxies.

    The overlook was gridlocked with cars by 4:30. By 5:30, cars were parked on both sides of Skyline drive and perhaps 500 people were at the overlook. Even as twilight overtook the sky, you could see bright meteors flashing across the western sky. Many stayed to watch sunrise over solid clouds as far as the eye could see.

  • While watching the showers from a field outside Athens, my co-gazers and I noticed something strange...
    around 5:00am we saw a pinprick of light move steadily (and rapidly) across the sky, at times growing quite bright, then fading again, but moving with constant velocity and completely traversing our field of view. This happened 2 more times over the next half-hour or so. Though none of us had seen such before, we suspected we were seeing satellites (perhaps the same one?). The lack of multi-colored lights and the small size ruled out the possibility of a plane, and we reasoned that the varying intensity of this pinprick could be attributed to a satellite's solar arrays reflecting varying amounts of sunlight in our direction.

    Did anyone else see these? Any explanations/comments?
  • You can see a graph of the Leonid storm [isthe.com] on my web site.

    There were many and frequent bright fireballs. During the peak of the storm (1015-1130 UTC), the sky was frequently filled with multiple meteors! Wow!

  • The meteor shower was really spectacular. From the front of our apartment in the suburbs of Cleveland, OH (clear sky, moderate noise pollution, streetlights at 50 feet distance), we managed to see 100-150 meteors (between 4.30-5.30 AM EST). Some of the meteors had green trails, anyone see something similar or have an idea why that happens ?
  • Woke my wife and 3-year old daughter to watch it on our back deck. Bundled up in heavy winter jackets. Between 2:15am and 3:00am PST, we saw one about every 5 seconds. Best show I've ever seen -- I've never seen more than one every 5 minutes before. On an average, non-meteor-shower night, I see about one every 20 minutes.

    There was a point they radiated from. If I looked there, instead of seeing long streaks, I saw bright spots that moved slightly then died out (rocks shooting straight at us). Scary.

    Many bright ones left trails for 5-10 seconds. One had a path that wasn't straight, it veered left about 1 degree at one point. I didn't notice any color in any of them. They didn't all radiate from the same point, some seemed to be going at large angles to the rest of them.

    My daughter said they were rocks falling from the sky, and catching fire, and they were brown and looked like big balls and they went really fast. We had trouble coaxing her outside because there were rocks falling from the sky.

    Nobody else in suburbia was out watching it. Several coworkers drove out to Pescadaro Beach and saw a good show. Good for them!

  • Despite partial cloudiness, we got up at 0230 MST to venture a few miles out onto the eastern plains, away from the light pollution from Abq.

    It was worth it, despite the cold weather!

    Like the other poster said - I saw more meteors in the first few minutes than in all my life up to that point.

    Put the futon into the back of the pick-up truck so we wouldn't crick our necks.

    Saw bursts of several in as many seconds, with intervals of no activity for no more than 20 seconds at a time.

    Two or three were pretty spectacular and bright, but not discernable as fireballs by my admittedly poor eyesight.

    About 2 or 3 years ago on a summer evening about 11pm MDT driving back from the city my wife saw a fireball - I thought it was lightning because of the flash, but then noticed there weren't any clouds!

    I'm still hoping to experience a total eclipse one of these years. I presume I'll have to venture away from North America to see it?

  • 12th floor, Union Square West (about 2 miles north of WTC site) Started watching (about 3:30AM EST) because I was kindly remined by a friend. I just assumed that I would be able to see them from the city, so I didn't bother making a note. But I went out to my balcony, and I could see them. Even one or two multiple instances. It was amazing. In the past the city has been too bright, or I was too young to attempt to stay awake that late, so this was my first. It was great. I can't wait for another chance. I'd love to see from on top of a mountain!
  • We all watched from here http://zeromag.com/toqer/shangrla.gif On my families ranch south of san jose (on mt uminum for those in the know)

    My wife and two friends left from our house around 11. We got up to the ranch, got out the burn barel (50 gallon oil drum with bullet holes) My other friends started to trickle in 15 minutes after we got up there.

    There was two small boys with us, they had never been on private property before. They had a blast. In between watching meteors we would make them go fetch more pine cones for the fire.

    We saw one meteor actually split and make a Y in the sky. Around 2:00am things really started to pick up. The meteors began falling in both series and parrelel, usually 5 at a time.

    We forgot to bring beer
