Solar activity was at moderate levels. Region 9901 (N21W26) produced an M4/1F flare on 12/1802 UTC with an associated Type IV Radio Sweep. Region 9893 (N20W39) has developed a delta magnetic configuration in the trailing spot and has increased in area and spot count. LASCO/EIT imagery indicates that Region 9893 is the most likely source of an optically uncorrelated M1.4 flare that occurred on 12/1310 UTC. Region 9906 (S16E26) has shown rapid growth in spot count, area, and now has a beta-gamma magnetic configuration. This region also shows some indication of a developing delta magnetic configuration. As Region 9907 (S05E61) rotates onto the disk it has revealed a moderate size spot group and a beta-gamma magnetic classification. One new region was numbered today: Region 9908 (N05W25).

Solar activity is expected to be moderate. Region 9893/9901 complex has been active and has two delta configurations. The potential for M-class events is good. Region 9906 and 9907 are developing and have a slight chance of M-class events.

The geomagnetic field was at quiet to unsettled levels with one 3 hour period of minor storm conditions. This isolated minor storm condition coincided with a sector boundary crossing. At the time of this issue the NASA/ACE EPAM data have shown a steady increase in low energy protons possibly due to expected CME shock.

The geomagnetic field is expected to be quiet to active. A CME shock is expected midday on day one of the forecast period. A second shock expected midday on day two of the forecast period.
