Solar Activity Report for 9/8/04
- View SourceLittle has changed since the last report, and there doesn't seem to be
any increase in the solar wind speed do to coronal hole influence at
this time. Sunspot region 671, near the western limb of the solar
disk, is growing rapidly, and has an outside chance of producing an
M-class flare before it rotates out of view. Despite the relative
lack of activity, there have been a few great aurora pictures captured
in Alaska, as can be seen here :
Northern autumn is the best time of year to see aurora, and that time
is almost upon us.
