Highlights of Solar and Geomagnetic Activity
22 - 28 December 2008
Solar activity was very low. The visible disk was spotless during the entire summary period. Four weak CMEs off the northeast limb were observed by SOHO Lasco imagery between 27/0530 - 27/1818 UTC.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during the entire summary period.
Geomagnetic field activity was at mostly quiet levels at all latitudes on 22-25 December. Isolated unsettled activity was observed during this period, with a single active period observed at high latitudes late on 23 December. This activity was due to a co-rotating interaction region, followed by a recurrent coronal hole high-speed stream. The geomagnetic field returned to quiet levels at all latitudes on 26 - 28 December. ACE solar wind measurements began the period with a speed of 299 km/s, reached a high of 578 km/s at 23/1419 UTC, and ended the summary period at 312 km/s. The Bz component of the IMF ranged between a low of -10 nT (22/1545 UTC) and a high of +9.8 nT (22/1626Z).
Forecast of Solar and Geomagnetic Activity
31 December 2008 - 26 January 2009
Solar activity is expected to be at very low levels.
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 02 - 06 January. Normal levels are expected 31 December - 01 January and again on 07 - 26 January.
Geomagnetic field activity is expected to be at quiet to unsettled levels during 31 December - 03 January due to a recurrent coronal hole high speed stream (CH HSS). Activity is expected to decrease to quiet levels during 04 - 17 January. Activity is expected to increase to unsettled levels during 18 - 19 January due to a CH HSS. Activity is expected to decrease to quiet levels during 20 - 26 January.
