Solar Activity Report for 10/02/04
- I'm tempted to say "see previous report" and leave it at that, because
very little has changed. Neither of the two sunspot regions visible
have the potential of generating significant flares at the present
time, and there are no coronal holes in sight. Even in very quiet
solar conditions as we have now, brief geomagnetic storms can still
pop up every now and then as a result of small solar wind gusts, and
the result can be some beautiful high-latitude aurora, as can be seen
from this picture taken in Yellowknife, Canada.
Northern hemisphere autumn is prime aurora season.
