Automated message just sent to me from:
http://aurorawatch.lancs.ac.uk/ and the first alert for some
considerable time. It's obviously in line with the Solar Storm
widely reported in the past 24hrs

Doubt if the cloud cover will allow me to have a good look out for it
tonight but I thought it was worth passing on to you all.

Activity needs to pick up first, too cloudy this evening in Sheffield
if it did pick up.


The red and orange alerts are for current conditions only. The "storm"
that generated the red alert has long since subsided.


Never mind, another one is on the way:

Sunspot AR1429 has unleashed another strong flare, an M6-class eruption
on March 9th at 0358 UT. The blast hurled a coronal mass ejection almost
directly toward Earth. According to analysts at the Goddard Space
Weather Lab, the CME will arrive on March 11th at 0649 UT (+/- 7 hr).
NOAA forecasters say the odds of a strong geomagnetic storm at that time
is 50%.
