Solar activity has been moderate, another M flare was observed from Region 9313 ( S07E41). This event, an M1/2f, began at 20/1834UTC and was accompanied by minor radio emissions, including a type II sweep. The flare developed into parallel ribbons and the filament running North from the region erupted during the event. A CME was also observed. The leader spots of this region, although small, are of mixed polarities resulting in a gamma magnetic configuration. A new region appears to be rotating on to the disk near S07. A small filament disappeared near S18 E09 sometime after 19/2137UTC.

Solar activity is expected to be low to moderate. Additional M class flares are possible from Region 9313. In addition, several regions, including Region 9289 (S06 L=205) are due to return over the next couple days. Major flares are possible if development in Region 9313 continues or if these regions return active.

The geomagnetic field has been mostly quiet to unsettled. A brief period of active conditions occurred around 0900UTC.

The geomagnetic field is expected to be generally quiet to unsettled early in the period. There is a good chance of active conditions later in the period as a result of recent activity in Region 9313.
