Highlights of Solar and Geomagnetic Activity
18 - 24 January 2010
Solar activity was at very low to moderate levels during the period. Region 1040 (N29, L=238, class/area Eki on 13 January) quietly rotated off the disk on 19 January. New Region 1041 (S25, L=052, class/area, 200/Eso on 22 January) rotated onto the disk on 19 January as a 10-spot, beta sunspot group. Prior to it rotating on the disk, the region produced an EUVI wave observed by STEREO-B at 17/0356 UTC. During this same period, SOHO C2 imagery indicated a
CME had lifted off the east limb. On 19 and 20 January, Region 1041 produced a total of six M-class x-ray events; the largest a M3.4/Sf at 20/1755 UTC. Activity decayed to mostly very low levels through the remainder of the period. New Region 1042 (N22, L=131, class/area, 190/Cao on 23 January) emerged on the disk on 22 January as a beta sunspot group. The region was quiet and stable.
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 predominately quiet during the period. The exceptions consisted of an interval of generally unsettled to active levels from 20/1500 UTC - 21/1200 UTC, and brief periods of unsettled to active levels at high latitudes from 0900 - 1500 UTC on 23 January and 0600 - 1500 UTC on 24 January.
Observations from
the ACE spacecraft indicated the onset of a co-rotating interaction region at 20/0900 UTC in advance of a coronal hole high speed stream. Solar wind velocity increased from 288 km/s at 20/0800 UTC to a maximum of 534 km/s at 20/2327 UTC, while density peaked at 19
p/cc at 20/1959 UTC. During this period, the southward component of the interplanetary magnetic field (IMF) ranged between +15nT and -17nT. Thereafter, the magnetic field decayed, while solar wind velocity steadily decreased, ending the summary period near 380
km/s.
Forecast of Solar and Geomagnetic Activity
27 January - 22 February 2010
Solar activity is expected to be at very low to low levels for the forecast period. Isolated moderate activity is possible from 14 - 22 February with the return of Region 1041 (S25, L=052
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. A period of unsettled to active levels are expected 16 - 17 February as a recurrent coronal hole high speed stream is expected to become geoeffective.
