Aurora Season Begins 16

MagnetarJones writes "Northern autumn began today at 55 minutes past midnight EDT (Sept. 23rd at 0455 UT), which means 'aurora season' is officially underway. Scientists aren't certain of all the reasons why, but there are more geomagnetic storms during autumn than other times of year. Already this month three such storms have triggered auroras visible as far south as the Carolinas in the United States. Some were so bright they cast shadows!"

    I've never seen them myself either, but I'd love to. According to this page [odysseymagazine.com],
    The best time to look for an aurora on any given night, unfortunately, is toward the middle of the night and into the morning (If you're an early riser that's okay!). It's always best to look for a weak green glow low in the northern sky. But when big disturbances occur, the aurora can be seen much earlier in the evening and much higher in the sky. If a bright display occurs early in the evening, there is a good chance that another display will follow a couple of hours later. Its colors can vary from green to red, and you can see much shimmering.
    You can also keep tabs on SPACE.com's 3-day Aurora Forecast [space.com] and keep an eye on SpaceWeather.com [spaceweather.com].

    If you want to see Aurora - and want your children to see aurora, visit the website for the International Dark Sky Assocation [darksky.org] and educate yourself and your friends about light pollution. Most people don't see them these days because glare and light pollution from lousy outdoor lighting blocks the view.

    And better yet, join IDA, even if you can't be active, your membership helps.

    Urge your local leaders to use full cut off, non-glaring outdoor lighting. Local action is VERY effective with dealing with light pollution.

    Futhermore, when you put a sheild on a light and direct the light downwards, you can use a less powerful lamp and save both energy and money.

    Oh, and by the way, that means less emmissions. Which means YOU can have an effect - and make MUCH more of a difference then just writing your Congress critter.

    Finally, if you really want to see aurora, get outside more often. You won't see them from in front of your CRT. They sometimes only last a few minutes, so don't depend on Email to alert you.

    Try signing up for AstroAlert at http://skyandtelescope.com/observing/proamcollab/a stroalert/article_332_1.asp. They send out email when there is solar activity that may trigger an aurora (usually 24-48 hrs in adavnce of the possible aurora). The cover best viewing times, and apr southern limit of the viewing. Great for people who don't live in Florida like I do.

    Sightings of Aurora should go to http://solar.spacew.com/www/auroras.html
