A large sunspot complex has rotated into view around the northeastern
limb of the Sun over the last several days. This spot complex is believed to
have been responsible for a major coronal mass ejection off the east limb of
the Sun on 14 October while it was still on the back side of the Sun (see
http://www.spacew.com/astroalert.html for details). At the present time, the
spot complex does not appear to be a highly probable source of major solar
flare activity. But this does not preclude the possibilty of observing
another coronal mass ejection from the area of this sunspot.
This spot complex has the size to become visible to the unaided (but
protected) eye, particularly as it rotates toward the central region of the
solar disc over the next 2 to 3 days.
A single comprehensive web page that is dynamically updated every 1 to 2
minutes has been setup to help monitor the Sun and the space environment.
This new resource is available at: http://www.spacew.com/plots.html. It
contains numerous plots to track current solar activity and space weather
conditions, as well as the latest SOHO spacecraft images and ground-based
H-alpha solar images. It also contains (to our knowledge) the most recent
SOHO "difference" images available anywhere on the Internet. These difference
images are particularly valuable for rapid and early detection of coronal
mass ejections.
