Solar activity was at low levels. Region 9794 (N12E23) was the most active region during the period and produced the largest flare of the day. This region produced a C3/Sf at 23/1337 UTC and an associated Type II radio sweep with an estimated shock velocity of 562 km/s. A second Type II radio sweep occurred in this region following an optical Sf flare at 23/0339 UTC, estimated shock velocity of 384 km/s. SOHO/LASCO imagery indicates neither of these radio sweeps will be geoeffective. This region also produced two other minor C-class flares early in the period. Regions 9783 (S11W65), 9787 (S07E06), and newly numbered Region 9799 (S25E54) also produced minor C-class flare activity during the period. Region 9788 (N17W14) did show some decay in the penumbral coverage since yesterday, although this region retains it's beta-gamma magnetic classification. New Regions 9795 (N23W60), 9796 (N09E18), 9797 (S16E32), and 9798 (S03E42) were also numbered today.

Solar activity is expected to be at low to moderate levels. Regions 9787 and 9788 magnetic structures possess the potential to produce M-class flares

The geomagnetic field activity was at quiet to unsettled levels.

The geomagnetic field activity is expected to be at quiet to unsettled levels through the forecast period.
