Highlights of Solar and Geomagnetic Activity
11 - 17 January 2010
Solar activity was at very low to low levels during the period. Region 1040 (N29, L=238, class/area Eki on 13 January) produced occasional B-class flares and isolated C-class flares, the largest event was a C2 flare 17/2223 UTC. Region 1040 also produced two long duration flares, a B8 flare at 14/2139 UTC and a C1 flare at 15/0841 UTC. Region 1040 maintained a Beta magnetic configuration during its transit.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels during the period.
Geomagnetic field activity was at predominantly quiet levels during the entire period. There was an isolated unsettled and active period observed at high latitudes on 11 January due to the arrival of a coronal hole high-speed stream. Observations from the ACE spacecraft showed solar wind speed varied between a low of 281 km/s at 11/0233 UTC to a high of 549 km/s at 11/1501 UTC. The density peaked at 10 p/cc at 11/0630 UTC. The southward component of the interplanetary magnetic field (IMF) ranged between +9 nT and -8 nT. A second coronal hole high-speed stream arrived on 13 January with little effect to the geomagnetic field.
Forecast of Solar and Geomagnetic Activity
20 January - 15 February 2010
Solar activity is expected to be at very low to low levels for the forecast period. Isolated moderate activity is possible from 20 January - 01 February with the return of old Region 1039 (S29, L052).
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels through the period.
The geomagnetic field is expected to be at predominantly quiet levels for the forecast period.
