Solar activity was at low levels. Analysis of recent data indicating a restructuring of the magnetic field and the materialization of satellite spots warranted the separation of the two main clusters of spots in Region 105 (now centered at S07W18). Newly numbered Region 114 (S12W02) is the trailing portion of spots previously included in Region 105. Region 114 produced the largest flare of the period, a C4.5/Sf at 14/1831 UTC, and at the time of this writing, data shows only a very weak delta class spot remaining indicating continued decay of this region. Region 105 produced several C-class events today, the largest was a C4.1/Sf flare occurring at 14/1453 UTC, this region has also shown decay during the period. H-alpha imagery suggests both these regions were simultaneously responsible for the intermittent and slightly elevated x-ray flux seen during the latter part of the day. The remaining numbered regions were quiet. New Region 115 (S03E45) was also assigned today.

Solar activity is expected to be at low to moderate levels. Regions 105 and 114 are both capable of producing M-class flare activity.

The geomagnetic field was at quiet to active levels. Coronal hole high speed stream effects subsided near mid-period. The greater than 2 MeV electron flux at geosynchronous orbit exceeded event threshold at 14/1130 UTC and remains at high levels.

The geomagnetic field is expected to return to quiet to unsettled conditions throughout the forecast period. Greater than 2 MeV electron flux is expected to be at moderate to high levels during much of the period.
