Aurora alert for tonight Bad Astronomy

I simply got word in the NOAA Space Weather Conjecture Center that Saturday s photo voltaic activity blew a wave of subatomic contaminants in the Sun that's reaching our planet now. They ranked this like a strong G3 event, meaning this is not harmful by itself but should spark aurorae at high latitudes.

If you reside at very north or very south (like southern Argentina, Australia, and so forth) latitudes, you need to get out at night and have a look. You may also look into the SWPC s aurora map to check on the chances of you seeing anything. Here s the map for that northern hemisphere by today at 21:00 UT (5:00 p.m. Eastern US time):

The fringes achieve as far south as where I'm in Colorado, therefore if it clears up later I ll have a look. And appearance back in the SWPC page I expect the results here on the planet can get more powerful for some time before dying off. Again, we re in no danger here, but hopefully we ll obtain a nice light show using this.
