Highlights of Solar and Geomagnetic Activity 06 - 12 February 2012

Solar activity began the week at moderate levels due to an M1/Sf flare produced by Region 1410 (N18, L=056, class/area Cso/240 on 01 February) at 06/2000 UTC. Activity levels decreased to very low to low levels for the remainder of the week. Noteworthy events include
a long duration C7 limb event from Region 1410 at 07/2219 UTC, and a CME associated with a filament eruption at 10/1154 UTC. Region 1410 produced a long duration C7 limb event at 07/2219 UTC.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit started the period at normal background levels, increased to moderate levels on 07 February, and reached high levels on 08-09 February. The electron flux returned to moderate levels for the remainder of the
period.

The geomagnetic field was at mostly quiet levels for the majority of the period. There were a few periods of unsettled to active conditions at mid-latitudes with active to minor storm conditions at high latitudes, early in the week on 7 and 8 February. This activity was associated with solar wind speeds between 450-500 km/s and periods of southward Bz. Mid-day on 09 February, unsettled to active periods were observed at high latitudes due to the arrival of a
co-rotating interaction region followed by a weak coronal hole high speed stream. From late on 09 February until the end of the period, mostly quiet conditions prevailed.

Forecast of Solar and Geomagnetic Activity 15 February - 12 March 2012

Solar activity is expected to be low with a slight chance of M-class activity until Region 1419 rotates off the visible disk on 26 February. Very low to low levels are expected to prevail for the remainder of the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels.

Geomagnetic field activity is expected to be at mostly quiet levels throughout the period, with the exception of any currently unanticipated future CME events. Increased field activity due to
recurrent disturbances is expected on 18-19 February, 23 February, 2-3 March, and 7 March.
