Highlights of Solar and Geomagnetic Activity
05 - 11 May 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 each day of the period.
Geomagnetic field activity was at quiet to unsettled levels on 05 May. Activity increased to active levels on 06 May. Activity decreased to quiet levels during 07 - 11 May. ACE solar wind
measurements indicated a recurrent coronal hole high-speed stream was in progress at the start of the summary period. Solar wind velocities reached a peak of 670 km/sec at 05/2319 UTC, then gradually decreased during the rest of the period (minimum velocity 318 km/sec at 11/2355 UTC). IMF Bt increased to a maximum of 6 nT at 05/0135 UTC, then ranged from 01 - 05 nT during the rest of the period. IMF Bz was variable in the + 05 nT range.
Forecast of Solar and Geomagnetic Activity
14 May - 09 June 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 21 - 28 May and 01 - 09 June.
Geomagnetic field activity is expected to be at quiet levels during 14 - 19 May. Activity is expected to increase to minor storm levels on 20 May with major storm levels possible at high latitudes due to a recurrent coronal hole high-speed stream. Activity is expected to
decrease to active levels on 21 May as high-speed stream effects begin to subside. Quiet to unsettled levels are expected during 22 May - 02 June. Quiet conditions are expected during 03 - 09 June.
