Highlights of Solar and Geomagnetic Activity
21 - 27 January 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.
The geomagnetic field was at mostly quiet levels during 21 - 24 January. Activity increased to active levels on 25 January. Activity decreased to mostly quiet levels for the balance of the period. ACE solar wind measurements indicated a recurrent coronal hole high-speed stream (HSS) was in progress at the start of the period. Peak velocity during this stream was 606.7 km/sec at 21/0107 UTC followed by a gradual decrease through 22 January. A solar sector
boundary crossing (away (+) to toward (-)) occurred during 22 - 23 January associated with increased proton densities (peak 9.6 p/cc at 23/2038 UTC) and increased IMF Bt (peak 5.9 nT at 22/1839 UTC). Another solar sector boundary crossing (toward (-) to away (+)) was
detected on 24 January in advance of a coronal hole-related co-rotating interaction region (CIR) and HSS. The CIR began late on 24 January and was associated with an increase in proton densities (peak 17.9 p/cc at 24/1302 UTC) and IMF changes including increased Bt (peak 10.2 nT at 25/0216 UTC) and intermittent periods of southward Bz (minimum -7.2 nT at 25/0458 UTC). Velocities associated with the HSS increased during 25 January and reached a peak of 574.1 km/sec at 25/0731 UTC, then gradually decreased during the rest of the period.
Forecast of Solar and Geomagnetic Activity
30 January - 25 February 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 03 - 24 February.
The geomagnetic field is expected to be quiet during 30 - 31 January. Activity is expected to increase to unsettled to active levels on 01 - 02 February due to the onset of a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 03 - 05 February as the high-speed stream gradually subsides. Quiet conditions are expected during 06 - 08 February. Activity is expected to increase to unsettled to active levels during 09 - 10 February due to another recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 11 - 13 February as coronal hole effects subside. Activity is expected to decrease to quiet levels during the rest of the period.
