Highlights of Solar and Geomagnetic Activity
02 - 08 June 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 was at normal levels through the period.
Geomagnetic field activity was at mostly quiet levels during 02 - 05 June. Activity increased to quiet to unsettled levels for the rest of the period. ACE solar wind measurements indicated a gradually subsiding recurrent high-speed stream was in progress at the start of the period. A peak solar wind velocity of 615 km/sec was detected at the start of the period. Velocities gradually decreased during 02 - 06 June with a low of 327 km/sec detected at 06/0213. A solar
sector boundary crossing (away (+) to toward (-)) occurred at approximately 07/0900 UTC. The boundary crossing was associated with an increase in velocities (peak 551 km/sec at 07/1604 UTC), increased IMF Bt (peak 10 nT at 0856 UTC), and periods of mostly
southward IMF Bz (minimum -7 nT at 07/0652 UTC). Velocities began to gradually decrease after 08/1400 UTC and reached a low of 302 km/sec by the close of the period.
Forecast of Solar and Geomagnetic Activity11 June - 07 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 19 - 23 June.
Geomagnetic field activity is expected to be at quiet levels during 11 - 15 June. Activity is expected to increase to unsettled levels during 16 - 19 June due a recurrent coronal hole high-speed wind stream. Activity is expected to decrease to quiet levels during 20 - 24 June. Activity is expected to increase to unsettled levels during 25 - 28 June due to a recurrent coronal hole high-speed wind stream. Activity is expected to decrease to quiet levels during 29 June - 02
July. Activity is expected to increase to unsettled levels during 03 - 05 July due to recurrence. Activity is expected to decrease to quiet levels during the last two days of the period.
