Solar activity has been moderate. Region 719 (S09E65) produced an M2.4 at 0854Z on 09 Jan which was accompanied by Type II radio emissions indicating a CME. Though it is reported as a small region, it continues to produce several plage fluctuations and point brightenings. Flare potential for this region remains fair. Region 718 (S06E54) continues to shrink, loosing another sunspot over yesterday with no other significant activity noted.

Solar activity is expected to be low. There does, however exist the slight chance that Region 719 will produce an isolated M-class flare.

The geomagnetic field has been at quiet to unsettled levels. The solar wind transient activity of the previous few days has subsided, with solar wind speeds returning to a nominal 450 km/s. The geomagnetic field did incur a 12 nT sudden impulse on 09 Jan at 1042Z, but it was of insufficient strength and duration to cause a storm-level response.

The geomagnetic field is expected to be at quiet to unsettled levels from 10 through 12 Jan. There is a possibility for an isolated period of active or minor storming levels on 12 Jan due to the grazing impact of a coronal hole induced high speed solar wind stream. The CME activity generated by the M-class activity of 09 Jan is strongly directed away from Earth, and is unlikely to generate elevated activity levels.
