Highlights of Solar and Geomagnetic Activity
05 - 11 January 2009

Solar activity was very low. New-cycle polarity Region 1010 (N19, L=021, class/area Bxo/050 on 11 January) emerged on 09 January. It produced isolated low-level B-class flares on 10 January, then gradually decayed during the rest of the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels throughout the period.

Geomagnetic field activity was at mostly quiet levels during the period. ACE solar wind measurements indicated no significant changes during the period. Solar wind velocities ranged from 275 to 453 km/sec. IMF Bz was variable in the -06 to +08 nT range while Bt ranged from 01 to 08 nT during the period.

Forecast of Solar and Geomagnetic Activity
14 January - 09 February 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 be at normal levels throughout the period.

The geomagnetic field is expected to be at quiet levels through 18 January. Field activity is expected to increase to quiet to unsettled levels, with isolated active periods possible at high
latitudes during 19 January due to a recurrent coronal hole high speed stream (CH HSS). Activity is expected to decrease to quiet levels during 20 - 26 January. Activity is expected to increase to quiet to unsettled levels, with isolated active levels possible at high latitudes during 27 - 30 January due to another recurrent CH HSS. Activity is expected to decrease to quiet levels during 31 January - 09 February.
