Highlights of Solar and Geomagnetic Activity
22 - 28 November 2010
Solar activity was at very low levels during the entire period. Region 1127 (N25, L=056, class/area Hsx/80 on 22 November) was the dominant region, producing the occasional B-class event. Region 1130 (N13, L=330, class/area Csi/60 on 28 November) emerged quickly on
the disk and was numbered late in the summary period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 12-27 November and was at low levels on 28 November.
The geomagnetic field was mostly quiet with isolated active periods (at high latitudes) during 22-23 November. Generally quiet levels prevailed from 24-27 November. Late on 27 November, from 1800-2400 UTC, activity increased to mostly unsettled to active levels with an isolated storm period. This increase in activity was due to the combined effects of a coronal hole high-speed stream (CHHSS) and a slow moving CME observed on 24 November. Quiet to unsettled levels were observed throughout the remainder of the period.
Forecast of Solar and Geomagnetic Activity
01 - 27 December 2010
Solar activity is expected to be at very low to low levels. There is a chance for an increase in C-class flare activity for 04-16 December with the return of longitudes associated with old Regions 1123 (S22, L=190) and 1124 (N14, L=171). Activity is expected to return to predominantly very low levels from 17-27 December.
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 for 01-10 December. An increase to high levels is possible for 10-17 December due to a recurrent CHHSS. Normal to moderate levels are expected for the remainder of the forecast period.
Geomagnetic field is expected to be predominantly quiet for 01-02 December. A small increase to quiet to unsettled levels is possible n 03-04 December due to a CME associated with a DSF. A return to quiet levels is expected from 06-10 December. Quiet to unsettled levels are possible for 11-15 December due to a recurrent CHHSS. Mostly quiet levels are expected for the remainder of the forecast period.
