Highlights of Solar and Geomagnetic Activity
23 February - 01 March 2009
Solar activity was very low. No flares were observed. New-cycle-polarity Region 1013 (N26, L=146, class/area Cso/020 on 24 February) emerged on 24 February. It gradually decayed to a spotless plage region on 27 February.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during the period.
Geomagnetic field activity was at mostly quiet levels during 23 - 26 February. Activity increased to quiet to unsettled levels on 27 February with minor to major storm periods at high latitudes.
Activity decreased to mostly quiet levels during the rest of the period. ACE solar wind data indicated the increased activity of 27 February was due to a recurrent coronal hole high-speed stream (CH HSS). The HSS began on 27 February. Velocities increased to a maximum of 701 km/sec at 27/2000 UTC, then gradually decreased for the rest of the period (minimum 384 km/sec at 01/2340 UTC). Interplanetary magnetic field changes associated with the onset of
the CH HSS included increased Bt (peak 11 nT at 27/0940 UTC), and brief, intermittent periods of southward Bz (minimum -7 nT at 27/1006 UTC).
Forecast of Solar and Geomagnetic Activity
04 - 30 March 2009
Solar activity is expected to be at very low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to increase to high levels during 14 - 18 March. Normal flux levels are expected during the rest of the period.
Geomagnetic field activity is expected to be at predominantly quiet levels through 12 March. Activity is expected to increase to quiet to active levels during 13 - 14 March with a chance for minor to major storm periods at high latitudes due to a recurrent CH HSS. Activity is expected to decrease to mostly quiet levels during 15 - 30 March.
