SOLAR ACTIVITY: A big new sunspot (AR1618) has emerged near the center
of the solar disk, and it is crackling with strong M-class solar flares.
NOAA forecasters estimate a 70% chance of more M-flares today, and a
15% chance of powerful X-flares. If the rapid growth of AR1618
continues apace, the Thanksgiving holiday (USA) could be filled with
stormy space weather. Check http://spaceweather.com for updates.
