Forecast of Solar and Geomagnetic Activity


06 June - 02 July 2007

Solar activity is expected to be at low to moderate levels with a slight chance for high activity until Region 960 rotates around the western limb on 14 June. Very low to low levels are expected from 15 - 28 June. Activity is expected to increase to low to moderate levels after 28 June due to the return of old Region 960 (S09, L=177).

There is a slight chance for a greater than 10 MeV proton event from significant flare activity from Region 960 through 14 June.

The greater than 2 MeV electron flux at geosynchronous orbit isexpected to be at normal levels during 06 - 19 June, high levelsduring 20 June - 01 July, and normal levels again on 02 July.

Quiet conditions are expected during 06 - 13 June. An increase to unsettled to active periods is expected during 14 - 15 June due to a recurrent coronal hole high-speed stream. Quiet to unsettled conditions are expected during 16 - 18 June. Another recurrent coronal hole high-speed stream is expected to affect the field during 19 - 23 June. Unsettled to minor storm conditions are expected during this time with major storm periods possible at high latitudes. Activity is expected to decrease to quiet to unsettled levels during 24 - 29 June. An increase to unsettled to active periods is expected during 30 June - 01 July due to a recurrent
coronal hole high-speed stream. Quiet conditions will return by 02 July.
