Highlights of Solar and Geomagnetic Activity
25 - 31 August 2008

Solar activity was very low. No flares were detected. The visible disk was spotless.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 25 - 26 August.

Geomagnetic field activity was at quiet levels at all latitudes during the period. ACE solar wind data indicated no significant changes during the period. Solar wind velocities ranged from 269 to 367 km/sec.

Forecast of Solar and Geomagnetic Activity
03 - 29 September 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 07 - 12 September and 15 - 22 September.

Geomagnetic field activity is expected to be at quiet levels during 03 - 04 September. Activity is expected to increase to active levels on 05 September due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet to unsettled levels during 06 - 07 September as the high-speed stream subsides. Quiet conditions are expected during 08 - 11 September. Activity is expected to increase to unsettled levels during 12 - 13 September. Activity is expected to increase to active to minor storm levels on 14 September due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to unsettled levels during 15 - 16 September as the high-speed stream subsides. Quiet conditions are expected during 17 - 29 September.
