look up!!!!! This should be great.  The Northern Lights should be getting
pretty wild for the next few days. See the space weather bulletin below.
This would be a good time to take the bus out in the evening with your
loved one(s). :-) (vanagon content)

SPACE WEATHER BULLETIN #01- 4
2001 April 10 at 10:26 a.m. MDT (2001 April 10 1626 UT)
**** MAJOR SOLAR ACTIVITY CONTINUES ****
        Another week of major solar activity is being produced from a large,
complex sunspot group currently making its way across the face of the sun.
The region is now near the center of the sun and has produced two
Earth-directed coronal mass ejections within the past 24 hours. This region
also produced an R3 (strong) radio blackout at 11:26 p.m. MDT on April 9
(2001 April 10 05:26 UTC) and was followed by a category S1 (minor) solar
radiation storm. Category R3 radio blackouts adversely affect high-frequency
radio communications and low-frequency navigation signals on the sunlit side
of Earth. A category S1 (minor) solar radiation storm will adversely affect
high-frequency radio communications in the polar regions.
        The region is expected to be visible from Earth for the next six
days and is likely to produce additional major events. Forecasters also
expect geomagnetic storms reaching category G2 (moderate) and possibly G3
(strong) geomagnetic storms to begin early on April 11 and continue through
April 12 as a result of the recent activity. Power systems, spacecraft
operations, and high-frequency radio communications are adversely affected
by geomagnetic storms. In addition, aurora may be visible as low as the
middle latitudes.
