Highlights of Solar and Geomagnetic Activity
22 - 28 September 2008
Solar activity was very low. No flares were detected. The visible disk was spotless during most of the period. However, Region 1002 (N25, L = 076, class/area Dso/030 on 22 September), a new
cycle-polarity spot group; emerged on 22 September, then decayed to
plage on 24 September.
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 the period. ACE solar wind measurements indicated minor changes during the period. Velocities ranged from 245 - 395 km/sec during the period. IMF Bt ranged from 01 - 07 nT and Bz ranged from -07 nT to
+07 nT during the period.
Forecast of Solar and Geomagnetic Activity
01 - 27 October 2008
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 reach high levels during 02 - 14 October.
Geomagnetic field activity is expected to be at active to minor storm levels on 01 October due to a recurrent coronal hole high-speed stream (CH HSS). Activity is expected to decrease to unsettled levels during 02 - 05 October as the CH HSS subsides. Quiet conditions are expected during 06 - 11 October. Activity is expected to increase to active levels on 12 October due to a recurrent CH HSS. Activity is expected to decrease to unsettled levels on 13 October as the CH HSS subsides. Quiet conditions are expected during 14 - 27 October.
