Another Solar Storm Approaching 59

Posted by timothy from the mind-yer-cell-phones-boys-it's-a-killer- dept.
RZG writes: "Aurora might be visible again across the mid-latitude portions of the U.S. and Europe, thanks to the CMEs (coronal mass ejections) associated with two powerful X class solar flares, and some smaller flares. The activity may begin in the next few hours, and last up to several days. The NOAA predicts another G3 class storm. Watch Spaceweather.com, the NOAA's space weather forcast, or this solar activity report for more information. The geomagnetic storm could cause power and satellite failures."

  • We had a "random" crash on our SQL server (which was running without a case) on tuesday when the solar flare happened. Is that a coincidence? Who knows. Still a bloody pain in the ass.

    Apparently the G4's are in such short supply that they couldn't even get one for this.

  • that is completely...TOTALLY incorrect! in fact it is hard to imagine a paragraph containing more bullshit pseudoscience than the post above. the aurora is NOT caused by thermal radiation in the upper atmosphere, it is caused by high energy particles (fast moving protons and electrons) slamming into the neutral atoms of gas of the atmosphere and ionizing them. when the electrons of the ionized atoms fall back to lower energy levels they emit light. it has nothing to do with "superheating of the atmosphere". there will be no effect on global warming(if indeed it is occuring) because the amount of energy deposited in the atmosphere by aurorae is miniscule compared with the huge amount of insolation the daytime side of the eath recieves every day. the arorae will NOT have any effect on atmospheric pollutants since pollutants are restricted amlost entirely to the troposphere and stratosphere and the aurora happen in the upper atmosphere(mesosphere). honest, you really dont need to make a hilariously innacurate post if you dont have a clue about the subject matter.

    What matters much is the polarity of the storm. IANA{astro-meteorolgist}, but I recall from a Discovery/Learning Channel show that a solar storm can be north or south polarized.

    If it's in-line with Earth's magnetic field, it tends to just flow around the planet without causing any major issues,

    If it's counter to our natural shielding, it causes spectacular light shows, messes with RF communication, disrupts electrical flow in the power grids (sags, spikes, outages), fries satellites, plays havoc with air traffic control and on-board aircraft systems, and causes people at high altitudes in the north polar regions (Canada and up) to see Yeti, Bigfoot and Elvis.
  • Being from Canada, the Aurora Borealis is nothing new to me, however, if this causes anything like the light shows we got here last summer, I'm not going to sleep until the storm is over.

    I've never seen boreali that bright with that many colours. Another thing was the size of them, I'm used to seeing a few strands and trailers on the northernmost edge of the sky. Last summer though, it filled the entire northern hemisphere of the sky with writhing, glowing, hissing (yes, up here you can actually hear them) fire strands.

    I can't think of a more impressive, beautiful sight. Not even the greatest sunset/rise came close to comparing to this. So if you want a really great show, book a trip up here to Calgary, or even better, some place further north like Edmonton or Ft. McMurray... this promises to be great.
  • Yeah. In '89 I was living in Albany, Western Australia (about 38S, from memory), and one night I was outside and we had the most magnificent aurora imaginable - which is unusual that far north, solar maximum or no.

    So for those of us who live at lower latitudes (I'm in Perth now, which is a few degrees further north again), this is really the only chance we'll get to see the aurora without travelling a long way.

    Incidentally, this storm probably isn't quite strong enough for us Aussies to see (possibly the southern tip of Tasmania might get some activity), but hopefully we will get some good aurorae in the near future.

  • A friend of mine, who is a bit on the paranoid side, (he is the kind who thinks that the world is out to get him) has been preparing for what he calls "planet buster" solar flares. He tells me that they could knock out the power grids of major cities.
    He has been preparing for the panic of the masses for years now, collecting rations, learning about survival, etc. I don't really know about the possible reality of this, but it seemed to be an amusing anectdote (sp) for this story.

  • The closest in site is just off Lexington Ave just north of 35W on the north side of town. Go north on Lexington from the 35W interchange. Take the first right (at stoplight where the road goes from 45MPH to 55MPH). Go past the tree line and find a place to park along the next field. Very few lights in the vacinity, and most are obstructed by the trees. The other places I only know how to get to them by landmarks, etc. Generally I head out north or north west of the cities. Usually along I35, 10, or I95. 10 seams to have the best places close in. Going south puts the MPLS/St Paul light bubble on the northren horizon right where one wants to look.

    I'm bummed. This one died off quickly. No show here in MPLS. The magnetic field of the storm had a southerly direction at the start, but it faded to a northerly one latter on. This turned off the display. Hopefully next time. We have a weak CME shockwave still to come, but I'm not expecting much.

  • It seems a little funnier now BOFH #6 [plig.net]
  • Actually, middle and and perhaps lower lattitudes will be able to view the aurora.

    From the Astro Alert
    Active sunspot region number 9026 spawned its third major X-class flare today. This one covered about as much area as yesterdays X2.3 flare, but was slightly less energetic at a class X1.2 x-ray intensity. Today's event also was associated with a coronal mass ejection, but the ejected mass was much more diffuse and difficult to spot. Nevertheless, it appears a second above-average velocity coronal mass ejection is now in-transit to the Earth. That disturbance will probably impact the Earth sometime on 10 June (early to mid UTC hours, perhaps). The impact of this second disturbance should be a bit less vigorous than the first disturbance that is due within the next 24 hours, but it may still be strong enough to renew minor geomagnetic and auroral storming through 10 and part of 11 June. The approach of the first high-velocity shock front from yesterdays X2 solar flare associated coronal mass ejection is currently visible in the form of increased densities of energetic protons in space near the Earth. These protons are thought to be accelerated by the shock front of the disturbance as it sweeps through space. Currently, energetic protons are reaching densities capable of producing intensified levels of ionization in the polar ionospheres of the Earth. This type of increased ionization is known as Polar Cap Absorption (or PCA) and can have a devastating impact on high frequency radio signals that propagate through the polar regions of the ionosphere. These energetic protons are not expected to decrease back toward background levels until after the shock front of the disturbance passes the Earth on 08 June. Most solar observatories are reporting that Region 9026, although it has lost some of it's areal coverage, has not changed signficantly in magnetic structure and is probably still capable of producing major M or X class solar flares. The frequency of minor and major flares from this region will probably begin to slacken off a bit over the next few days unless renewed growth occurs.

  • Ummm - no.

    If the Van Allen belts shielded us 100%, there wouldn't be any auroras to be seen, would there? The magnetic field of the planet causes "holes" in the belts approaching the poles.

    So, your dose will be higher if you're in Nome or Thule tonight, but folks down in Brasilia shouldn't let this get to them (although folks down in Rio have the South Atlantic Anamoly to worry about).

  • Anytime you have a moving electrical current (as in solar wind) crossing a magnetic field (as in Earth) it generates heat. (Works the other way also.) Thus the Aurora is formed from the superheating of a portion of the atmosphere. During a period of global warming this can't help our heat balance to have these large solar storms boosting the heat balance of the planet. Of course, the superheating of polar gases may have some effect on the makeup of the atmosphere (as in burn off the nasties, or create more ozone.)

  • Actually, the last time a solar storm this scale happened, in 1989 IIRC, people flying over the north pole (such as from northern Europe to the east coast of the USA) got something like 10,000 X-Rays worth of radiation. The van allen belts don't cover the areas around the magnetic poles.
