Solar activity was at low levels. Several weak C-class flares occurred throughout the period, from sources including most of the larger active regions on the visible disk. The largest event of the period was a C4/Sf at 04/2306 UTC, from a source near newly numbered Region 9895 (N06E58). Two other regions were numbered today, 9894 (N14W09), and 9896 (S11E74). Newly numbered Region 9896 appears to be the return of old Region 9866, which was a source of several energetic flares on its last transit. It now appears as a large, single polarity spot (possibly the leading spot of a large bipolar group), though lacks any evident bright plage area as would be expected for an energetic region. It's present position near the east limb prevents detailed analysis.

Solar activity is expected to be predominantly low to moderate, though a chance for an isolated major flare exists, particularly for the emergent regions near the east limb.

The geomagnetic field was predominantly quiet, with an isolated unsettled period observed at higher latitudes during 05/1800-2100 UTC. The greater than 2 MeV electron flux observed at geosynchronous orbit was again at high levels today.

Geomagnetic activity is expected to be mainly quiet to unsettled. A chance for isolated active periods exists for days two and three of the forecast period. Greater than 2 MeV electron flux is expected to remain above event threshold for most of the period.
