Forecast of Solar and Geomagnetic Activity
19 September - 15 October 2007

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 reach high levels during 24 September - 10 October.Geomagnetic field activity is expected to be at quiet to unsettled levels during 19 - 22 September. Activity is expected to increase to unsettled to active levels during 23 - 24 September due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet to unsettled levels during 25 - 28 September as the stream subsides. Activity is expected to increase to unsettled to minor storm levels during 29 - 30 September due to another recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet to unsettled levels during 01 - 02 October.

Activity is expected to increase to unsettled to active levels during 03 - 04 October due to another recurrent coronal hole high-speed stream. Mostly quiet conditions are expected during the remainder of the period.
