Weekly Highlights and Forecasts
Highlights of Solar and Geomagnetic Activity 12 - 18 December 2011
Solar activity was at very low to low levels. Region 1367 (S19, L=076, class/area Cso/030 on 08 December) was the most active region and produced occasional to frequent C-class flares near and beyond the west limb during 13-15 December. Region 1376 (N20, L=306, class/area Dro/020 on 18 December) was also responsible for producing multiple C-class flares during 17-18 December. There were no Earth-directed coronal mass ejections observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels.
Geomagnetic field activity was at mostly quiet levels during most of the period, with isolated periods of unsettled levels observed at high latitudes.
Forecast of Solar and Geomagnetic Activity 21 December - 16 January 2012
Solar activity is expected to be at low levels during 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 normal to moderate levels during the period.
Geomagnetic field activity is expected to be at quiet levels during 21-27 December. Activity is expected to increase to quiet to unsettled levels during 28-29 December and 5-6 January due to recurrent coronal hole high-speed streams. Quiet levels will prevail 30 December - 4 January and 7-16 January.
