Highlights of Solar and Geomagnetic Activity
16 - 22 June 2008
Solar activity was very low. No flares were detected. Region 999 (S02, L=206, class/area Hsx/020 on 17 June) was the only spotted region on the disk during the summary period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 16 - 19 June and 22 June.
Geomagnetic field activity was at quiet to active levels on 16 June. Activity decreased to quiet to unsettled levels during 17 - 19 June. Activity increased to quiet to active levels on 20 June. Activity decreased to mostly quiet levels for the rest of the period. ACE solar wind measurements indicated a recurrent coronal hole high-speed stream occurred during the period. Velocities increased through early 17 June with a peak of 784 km/sec detected at 17/0248
UTC, then gradually decreased through 19 June. Another brief increase in velocities occurred from late 19 June into early 20 June with a peak of 613 km/sec detected at 20/1032 UTC. The velocity increase was accompanied by increased IMF Bt (peak 9 nT at 19/2340 UTC), periods of enhanced southward IMF Bz (minimum -8 nT at 20/0222 UTC), and a minor increase in proton densities. Velocities gradually decreased for the rest of the period and reached a minimum of 408 km/sec by the close of the period.
Forecast of Solar and Geomagnetic Activity
25 June - 21 July 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 25 June and 13 - 21 July.
Geomagnetic field activity is expected to be at quiet to unsettled levels during 25 June - 11 July. Activity is expected to increase to active levels during 12 - 13 July due to a recurrent coronal hole high- speed stream. Activity is expected to decrease to unsettled levels during 14 - 17 July as the high-speed stream gradually subsides. Activity is expected to decrease to quiet levels for the rest of the period.
