Hello people... Sorry if some of you receive twice, but I have chosen to send this to my general astronomy list as well as the aurora list... I have good reason.
 
This is the biggest X-class flare I have ever seen!!!
 
At 1105 UTC an X-17.2 solar flare erupted from active region 486. The region producing this flare is almost on the solar meridian meaning we are likely to be in the direct line of fire.
 
This could be the BIG ONE!! If this flare acts the way we are thinking it will, then we will be in for a superb auroral display in the coming 36 hours...
 
I'll be in touch...
 
 
At present, solar conditions are these: velocity is 835 km/sec. Density is 1.7. Bt is 11.2 and the Bz is + 2.2. The predicted Kp index for the next hour is 4+.
Solar activity is still high, and further eruptions are expected to continue over the next 72 hours.
 
For latest conditions, see http://www.spacew.com/plots.html, discussion see http://www.spacew.com/aurora/forum.html or if you do see an aurora you can post your observations here: http://www.spacew.com/www/subaurora.html.
Good luck!
