Highlights of Solar and Geomagnetic Activity
14 - 20 June 2010
Solar activity ranged from very low to low levels during the period. Activity was at low levels on 14 June, due to a C1/SF flare at 14/0051 UTC from Region 1081 (N25, L=101, class/area Bxo/010, on 14 June). Activity decreased to very low levels for the remainder of the period (15-20 June) with Region 1082 (N27, L=306, class/area Dso/030, on 20 June) producing a B5/SF flare at 17/1033 UTC.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux levels at geosynchronous orbit was at normal to moderate levels during 14-16 June. Flux levels increased to high levels during 17-20 June.
The geomagnetic field ranged from quiet to unsettled levels, with minor and major storms at high latitudes. On 14 June, the geomagnetic field was at quiet levels, with isolated unsettled levels at high latitudes. Activity increased to quiet to active levels, with minor and major storm levels occurring on 15-16 June. Activity decreased on 17 June, with quiet to unsettled levels and an isolated major storm period at high latitudes between 17/06-09 UTC. The disturbances during 15-17 June were associated with a recurrent coronal hole high-speed stream (CH HSS). During this period, solar wind data from the ACE spacecraft indicated elevated wind speeds at 602 km/s at 16/0825 UTC, with increased IMF total field intensity of 12 nT at 15/1228 UTC, with intervals of southward IMF Bz to -9 nT at 16/0126 UTC, and increased density to 22 p/cc at 15/0742 UTC. The geomagnetic field decreased to quiet levels for the remainder of the period, 18-20 June.
Forecast of Solar and Geomagnetic Activity
23 June - 19 July 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 high levels for most of the forecast period due to recurrent high speed streams with the exception of 23-25 June and 11-13 July when the background is expected to decrease to normal levels.
Geomagnetic field activity is expected to be at predominantly quiet levels during 23-24 June. Quiet to unsettled levels, with isolated active levels at mid-latitudes and isolated minor storm levels at high latitudes, are expected during 25 June - 01 July, due to a recurrent CH HSS. Activity is expected to decrease to predominantly quiet levels from 02-11 June. Activity is expected to increase to quiet to unsettled levels, with isolated active levels, on 12 -14 July, due to another recurrent CH HSS. Predominantly quiet levels are expected for the remainder of the forecast period, 15-19 July.
