Highlights of Solar and Geomagnetic Activity
01 January 2008 - 24 December 2007

Solar activity was very low to low. Activity was at very low levels through 29 December. Solar activity reached low levels due to a C1.7 flare observed at 30/2005 UTC. The most likely origin of the flare was from a brightening on the east limb near where old Region 978 (S08, L=223) is expected to return.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels 24 - 27 and 29 - 30 December.

The geomagnetic field was quiet throughout the summary period.

Forecast of Solar and Geomagnetic Activity
02 - 28 January 2008

Solar activity is expected to be very low to low. Isolated M-class activity is possible during 01 - 13 January due to the return of old Region 978.

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 - 08 January, 12 - 13 January, and 14 - 28 January.

The geomagnetic field is expected to be at quiet levels during 02 - 05 January. Activity is expected to increase to unsettled levels during 06 - 08 January due to recurrence. Activity is expected to decrease to quiet levels during 09 - 12 January. Activity is expected to increase to unsettled to active levels during 13 - 16 January due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet to unsettled levels for the rest of the period as the high-speed stream subsides.
