Highlights of Solar and Geomagnetic Activity
20 - 26 April 2009

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

Geomagnetic field activity was at quiet levels during most of the period. ACE observations indicated no significant activity in the solar wind during the period.

Forecast of Solar and Geomagnetic Activity
29 April - 25 May 2009

Solar activity is expected to be very low.

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 08 - 11 May. Normal flux levels are expected during the rest of the period.

Geomagnetic field activity is expected to be at mostly quiet levels through 05 May. Activity is expected to increase to quiet to unsettled levels during 06 - 09 May, with active conditions possible on 06 May, due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to predominantly quiet levels during 10 - 25 May.
