Solar activity remained at low levels; however, frequent C-class events occurred throughout the period. Region 9238 (S22W48) produced a long duration C5/1f flare and CME at 23/0547Z. Region 8231 (S23W62) produced several C-class flares, the largest being an impulsive C7/1n flare at 23/1424Z. A long duration C7 flare and CME in Region 8239 (S21E49) began at around 23/1930Z and remains in progress. Region 9236 (N21E06), though not as active as yesterday, retains moderate complexity and displayed increased activity late in the period. New region 9241 (N21W19) was numbered today.

Solar activity is expected to be moderate. Regions 9231 and 9236 will still be the likely source of isolated M-class activity. Activity near the east limb may also result in M-class flares.

The geomagnetic field was quiet to unsettled with an isolated active period between 23/03 - 06Z.

The geomagnetic field is expected to continue at mostly quiet to unsettled levels through day two. Field activity is expected to increase to active to minor storm levels on day three due to the CME observed today at 23/0547Z.
