Highlights of Solar and Geomagnetic Activity
10 - 16 May 2010
10 - 16 May 2010
Solar activity was very low. A few low-level B-class events were observed early in the week. The solar disk was void of sunspots throughout the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period.
The geomagnetic field was predominantly quiet throughout the period, with the exception of some isolated unsettled periods and a single isolated active period at high latitudes on 11-12 May.
Forecast of Solar and Geomagnetic Activity
19 May - 14 June 2010
Solar activity is expected to be at very low to low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal background levels for most of the period. However, increases to high levels are possible on 31 May - 06 June and 11-12 June in response to recurrent high speed streams.
Geomagnetic field activity is expected to be quiet for 19 May, and is expected to increase to mostly unsettled levels for 20-22 May in response to a favorably positioned coronal hole. Quiet levels are expected for 23-28 May. An increase to active levels is expected for 29-30 May in response to a recurrent high speed stream. Activity should decline to mostly unsettled levels for 31 May. Quiet levels are expected to predominate from 01-10 June. Quiet to unsettled
levels are possible on 08-09 June in response to another recurrent high speed stream, and quiet levels should return from 10-14 June.
