Highlights of Solar and Geomagnetic Activity
28 September - 04 October 2009
Solar activity was very low. Region 1027 (N24, L=240, class/area Dao/110 on 24 September) produced a B7 flare on 01 October as it was nearing the west limb. No flare activity occurred during the remainder of the period.
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 quiet to active levels on 28 September with brief minor storm conditions at high latitudes. Activity decreased to quiet levels during the remainder of the
period. A geomagnetic sudden impulse (18 nT, as measured by the Boulder USGS magnetometer) was detected at 04/0422 UTC. ACE solar wind measurements indicated the 28 September activity was associated with a period of southward IMF Bz (minimum -6 nT at 28/0530 UTC) and enhanced IMF Bt (peak 8 nT at 28/0534 UTC). ACE data indicated the
sudden impulse was associated with a weak interplanetary shock. A velocity increase (approximately 297 to 362 km/sec) and increased IMF Bt were associated with the sudden impulse. There was no obvious source for the sudden impulse.
Forecast of Solar and Geomagnetic Activity
07 October - 02 November 2009
Solar activity is expected to be very low.
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.
Geomagnetic field activity is expected to be at quiet levels during most of the period. However, unsettled conditions are expected during 24 - 25 October due to recurrence.
