Highlights of Solar and Geomagnetic Activity
23 - 29 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 reached high levels during 23 - 24, 27, and 29 June.
Geomagnetic field activity was at quiet levels until late on 24 June when activity increased to unsettled levels. A further increase to active levels occurred during 25 - 26 June with minor to major storm levels at high latitudes. Activity decreased to quiet to unsettled levels for the remainder of the period. ACE solar wind measurements indicated a co-rotating interaction region (CIR) occurred during 24 - 25 June in advance of a recurrent coronal hole high-speed stream (HSS). The CIR was associated with increased proton densities (peak 20 p/cc at 24/2251 UTC), a solar sector boundary crossing (toward (-) to away (+)), and changes in the interplanetary magnetic field (IMF). IMF changes included increased Bt (peak 15 nT at 25/1710 UTC) and intermittent periods of southward Bz (minimum -10 nT at 25/1735 UTC). The HSS commenced on 25 June, reached a peak velocity of 686 km/sec at 26/1846 UTC, then began to gradually subside on 28 June. Solar wind velocities decreased to a low of 470 km/sec by the end of the period.
Forecast of Solar and Geomagnetic Activity
02 - 28 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 13 - 21 July.
Geomagnetic field activity is expected to be at quiet to unsettled levels during 02 - 11 July. Activity is expected to increase to active levels during 12 - 13 July with storm levels possible at high latitudes 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 during 18 - 21 July. Activity is expected to increase to unsettled levels during 22 - 24 July due to recurrence. Activity is expected to decrease to quiet levels during 25 - 28 July.
