Highlights of Solar and Geomagnetic Activity
05 - 11 July 2010


Solar activity was at very low to low levels during the period. Activity was very low during 05 - 07 July due to isolated to occasional low-level B-class flares. Activity increased to low levels during 08 - 09 July due to isolated C-class flares from Region 1087 (N19, L =334, class/area Ero/120 on 11 July), the largest of which was a C3/Sf at 09/2002 UTC. Activity decreased to very low levels on 10 - 11 July with only isolated B-class flares from Region 1087.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during 05 July - 11 July.

Geomagnetic field activity was predominantly at quiet levels from 05 - 11 July.

Forecast of Solar and Geomagnetic Activity
14 July - 09 August 2010


Solar activity is expected to be at very low to low levels during 14 - 21 July with a chance for isolated C-class flares and a slight chance for an M-class flare from Region 1087. Activity is expected to decrease to very low levels on 22 July as Region 1087 departs the visible disk. Activity is expected to increase once again to very low to low levels during 04 - 09 Aug with a chance for isolated C-class flares and a slight chance for an M-class flare as Old Region 1087 rotates back onto the 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 14 - 19 July, and 26 July – 08 Aug. Normal to moderate flux levels are expected during the remainder of the period.

Geomagnetic field activity is expected to be at quiet to unsettled levels during 14 - 15 July, with a chance for active levels on 14 July, due to recurrent coronal hole high-speed stream (CH HSS) effects. Quiet conditions are expected during 16 - 22 July as the CH HSS rotates out of a geoeffective position. A second round of recurrent CH HSS effects are forecast for 23 - 29 July with unsettled to minor storm levels expected on 23 July, quiet to active levels expected on 24 July, and predominately quiet to unsettled levels expected during 25 - 29 July. Quiet conditions are expected during 30 July - 08 Aug as the effects from the CH HSS subside.
Geomagnetic field activity is expected to increase once again to quiet to unsettled due to effects from a third recurrent CH HSS.
