Solar activity was low. Several low C-class flares were observed throughout the period. Region 501 (N03W72) is undergoing considerable decay as it approaches the west limb, but is still producing isolated C-class flares. Region 508 (S17E08) was responsible for most of the low C-class activity. No significant change was noted in this moderately complex region over the last 24 hours. It maintains a beta-gamma configuration in approximately 450 millionths of white light areal coverage. Region 507 (N09W03) is the largest and most complex region on the visible disk, but was rather quiet this period. A weak delta configuration is apparent in this spot group with over 700 millionths of areal coverage. New Regions 509 (S10E56) and 510 (S22E62) were numbered today. Region 509 produced a C2/Sf flare at 24/1854Z.

Solar activity is expected to be at low to moderate levels. An isolated M-class flare is possible, primarily from Regions 501, 507, and 508.

The geomagnetic field was quiet to unsettled with isolated active periods in the higher latitudes. A well positioned coronal hole is producing solar wind speeds near 600 km/s, creating a weak disturbance in the geomagnetic field. The greater than 2 MeV electrons at geosynchronous orbit were at high levels today.

The geomagnetic field is expected to continue at quiet to active levels through 26 November. Isolated minor storm levels are also expected, but will be confined mostly to higher latitudes. Quiet to unsettled levels are expected on 27 November as the current disturbance subsides.
