Highlights of Solar and Geomagnetic Activity
27 April - 03 May 2009


Solar activity was very low. Region 1016 (S08, L=106, class/area, Cao/020 on 29 April) formed on the disk and decayed into spotless plage by 01 May. As the region approached the west limb, it produced a B2 x-ray flare at 01/0858 UTC.

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 the entire period. ACE observations indicated no significant activity in the solar wind during the period.

Forecast of Solar and Geomagnetic Activity
06 May - 01 June 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 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 May - 01 June.
