SUNSPOT SURPRISE: Barely visible only 24 hours ago, a new sunspot group big
enough to swallow Earth is bubbling up through the solar surface. So far
the active region poses no threat for strong solar flares, but this could
change if its rapid growth continues. Visit today's edition of
Spaceweather.com to view a movie of sunspot genesis, and to learn how this
development fits in with the recent "crash" of the sunspot cycle.
 
HIGH-LATITUDE AURORA WATCH: A hole in the sun's atmosphere is spewing a
stream of solar wind toward Earth. High-latitude sky watchers should be
alert for auroras when the stream arrives on Jan. 27-28. Monitor the
realtime aurora gallery for sightings.
