p.1 #1 · p.1 #1 · Aurora Borealis threat now over North America


"STRONG COMPRESSION OF EARTH'S MAGNETOSPHERE: As expected, a double CME hit Earth's magnetic field on June 16th around 0900 UT. Intitially, the impact appeared to be weak, but now the effects are growing. Analysts at the Goddard Space Weather Lab say the impact strongly compressed Earth's magnetic field, directly exposing some geosynchronous satellites to solar wind plasma. Geomagnetic storms and auroras are possible in tthe hours ahead. "

http://www.spacew.com/plots.php (watch for Bz to drop south -- if it goes very far negatively... say -20 or more... then most dark sky locations could capture something nice... even down south) Upper tier states and Canada should definitely see something if clear. (basically... higher the latitude the better for you)

Moonpeep,
Is an accurate translation of your message, "Damn! Sun spots are going to knock the northern lights all the way down to Nashville."

Could. The energy from the solar eruption hit earth. We're just waiting to see if it becomes effective visually. Things are tricky to forecast. Gotta look at the Bz index (want a very negative number) and the Kp index. (higher the better) Right now I doubt you could see them down there... but if those values swing the way they need to you could.

7-12-2012:

Major X class flare -- seemingly directed at earth! Could produce wide-spread auroral activity around the US within the next few days.
