Forecast of Solar and Geomagnetic Activity
Solar activity is expected to be at very low levels. However, there will be a slight chance for low activity (isolated low-level C-class flares) during 20 November - 03 December with the return of (old) Region 1007 (N35, L=252) to the visible disk.
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 12 - 15 November, 26 November - 03 December, and again during 06 - 08 December.
Geomagnetic field activity is expected to be at quiet levels during 12 - 23 November. Activity is expected to increase to mostly unsettled levels during 24 - 28 November due to a recurrent CH HSS. Quiet levels are expected during 29 November - 02 December followed by an increase to unsettled to isolated active levels during 03 - 06 December due to another recurrent CH HSS. Activity is expected to be mostly quiet during 07 - 08 December as the HSS subsides.
