Highlights of Solar and Geomagnetic Activity
15 - 21 December 2008
Solar activity was very low. The visible disk was spotless during the entire summary period.
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 during the period. Isolated unsettled activity was observed at high latitudes late on 17 December due to a brief excursion of southward Bz (-5 nT at 17/1400 UTC) as measured at ACE. During the summary period, ACE solar wind measurements varied between a high of 377 km/s at 17/0338 UTC to a low of 278 km/s at 21/1833 UTC. The Bz component of the IMF varied between a low of -6.8 nT at 17/0101 UTC to a high of +8.5 nT at 17/0255 UTC.
Forecast of Solar and Geomagnetic Activity
24 December 2008 - 19 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 24 December - 01 January and again on 07 - 19 January.
Geomagnetic field activity is expected to be at quiet levels during 24 - 30 December. Activity is expected to increase to unsettled levels during 31 December - 02 January due to a recurrent coronal hole high speed stream. Activity is expected to decrease to quiet levels during 03 - 17 January. Activity is expected to increase to unsettled levels during 18 - 19 January.
