Highlights of Solar and Geomagnetic Activity
16 - 22 February 2009

Solar activity was very low. No flares were observed. The visible disk was spotless.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during 16 - 18 February.

Geomagnetic field activity was at quiet levels during most of the period. ACE solar wind velocities decreased from 523 to 282 km/sec during 16 - 18 February as a recurrent coronal hole high-speed stream (CH HSS) subsided. Solar wind velocities gradually increased from 282 to 490 km/sec during 19 - 22 February, possibly due to a recurrent HSS. During this period, IMF Bz varied from +08 to -06 nT and IMF Bt ranged from 01 to 10 nT.

Forecast of Solar and Geomagnetic Activity
25 February - 23 March 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 increase to high levels during 14 - 18 March. Normal flux levels are expected during the rest of the period.

Geomagnetic field activity is expected to be at predominantly quiet levels during 25 February - 12 March. Activity is expected to increase to quiet to active levels during 13 - 14 March with storm periods possible at high latitudes due to a recurrent CH HSS. Activity is expected to decrease to mostly quiet levels during 15 - 23 March.
