Highlights of Solar and Geomagnetic Activity
17 - 23 August 2009
Solar activity was very low. No flares were observed. The visible disk was spotless.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during 17 - 21 August. Fluxes increased to normal to moderate levels during 22 - 23 August.
Geomagnetic field activity was at quiet levels during 17 - 18 August. Activity increased to quiet to active levels on 19 August, with a single minor storm period observed at high latitudes. Activity decreased to quiet to active levels during 20 - 21 August, with isolated active periods at high latitudes. ACE solar wind data indicated the elevated conditions were due to a recurrent coronal hole high-speed stream (CH HSS). Predominantly quiet levels returned during 22 - 23 August. Velocities at ACE increased from a low of 269 km/s at 17/0758 UTC to a high of 594 km/s at 20/2245 UTC before gradually decreasing to 421 km/s at the end of the period.
Interplanetary magnetic field activity associated with the CH HSS included increased Bt (maximum of 12 nT at 19/1551 UTC) and southward Bz (maximum of -10 nT at 19/1135 UTC).
Forecast of Solar and Geomagnetic Activity
26 August - 21 September 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 to moderate flux levels during the period.
Geomagnetic field activity is expected to be at mostly quiet levels during the period. Isolated unsettled levels are expected on 02 September, 09 September, and 16 - 17 September due to recurrent effects.
