Solar activity has been low. Region 9283 (S12E39) produced two events of equal magnitude, C5/Sf, representing the greatest activity for the period. The first was in progress at the beginning of the period, peaking at 24/2101 UTC, and the second occurred at 25/1600 UTC. Other activity included several lesser C-class flares from Region 9283, and a C2/Sf from Region 9280 (N09W04). Optical reports of filament disruptions near S36W45 and N30W60 were received (at 25/0432 and 25/1213 UTC, respectively), and while no correlated SOHO/LASCO observations are available at present, a lack of corresponding radio activity suggests no significant associated CMEs. New Region 9287 (S16E60) was numbered today. Also of note - a partial solar eclipse occurred over most of North America today, from 25/1615 to 1815 UTC, with only minor impacts on solar optical and radio observation sites.

Solar activity is expected to be low to moderate. Regions 9280 and 9283 are the most likely sources for isolated M-class activity.

The geomagnetic field was at quiet to unsettled levels.

Geomagnetic field activity is expected to persist at quiet to unsettled levels for the next three days.
