Highlights of Solar and Geomagnetic Activity
27 August - 02 September 2007
Solar activity was very low.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 28 - 31 August and again on 02 September.
The geomagnetic field was at quiet to active levels during 27 - 28 August with brief minor to major storm periods detected at middle and high latitudes, respectively, on 28 August. Activity declined to quiet levels at all latitudes during 29 - 30 August. Activity increased to quiet to unsettled levels during 31 August - 01 September with active to minor storm periods detected at high latitudes on 01 September. A further increase to quiet to minor storm levels occurred on the last day of the period with major storm periods detected at high latitudes. ACE solar wind data indicated two recurrent high speed streams affected the field during the summary period. The first stream commenced late on 26 August and eventually reached a peak velocity of 695 km/sec at 27/1848 UTC. The proton density increase in advance of this stream reached a peak of 71 p/cc at 26/1627 UTC. IMF variance associated with the stream included a peak IMF Bt of 21 nT at 26/1711 UTC and a minimum IMF Bz reading of -12 nT at 26/1952 UTC. The second stream commenced late on 31 August and eventually reached a peak velocity of 682 km/sec at 02/2141 UTC. The proton density increase in advance of this stream was negligible. IMF variance associated with the stream included a peak IMF Bt of 11 nT at 01/2354 UTC and a minimum IMF Bz reading of -09 nT at 02/00001 UTC.
Forecast of Solar and Geomagnetic Activity
05 September - 01 October 2007
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 05 - 10 September and 24 September - 01 October.
.
Geomagnetic field activity is expected to be at quiet levels on 05 September. Activity is expected to increase to unsettled to active levels on 06 September due to a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 07 - 28 September. Activity is expected to increase to unsettled to minor storm levels during 29 - 30 September as another recurrent coronal hole high-speed stream affects the field. Activity is expected to decrease to quiet to unsettled levels on 01 October as coronal hole effects subside.
