Highlights of Solar and Geomagnetic Activity
07 - 13 June 2010
Solar activity ranged from very low to moderate levels. Very low levels prevailed from 07-11 June, but activity increased to moderate on 12 June due to an M2/Sn flare at 0057 UTC from Region 1081 (N24, L=99, class/area Dao/90 on 13 June), which was associated with a type II radio sweep and a Tenflare. There was a weak CME associated with this event but it was not earthward directed. Region 1081 grew quickly after being assigned on 11 June but seemed to be stabilizing or possibly decaying late on 13 June. An additional M1/Sf occurred on 13 June at 0539 UTC from Region 1079 (S24, L=123, class/area Bxo/10 on 12 June) which also had an associated Type II radio sweep. A CME was observed off the West limb in association with this event. The spot class and area for Region 1079 on 13 June were highly uncertain due to its location on the west limb.
No proton events were observed at geosynchronous orbit. A weak enhancement of proton flux levels was noted between 0600-1000 UTC on 12 June, most likely related to the M2 event that occurred at 12/0057 UTC.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period.
The geomagnetic field was predominantly quiet during the week with the exception of some isolated unsettled periods and an isolated active period at high latitudes on 13 June. Solar wind data from the ACE spacecraft showed generally nominal conditions with the exception of a weak coronal hole high speed stream on 10 June and a solar sector boundary change that started late on 12 June.
Forecast of Solar and Geomagnetic Activity
16 June - 12 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 normal background levels for the most of the forecast period with the exception of 17-18 June and 27 June - 03 July due to recurrent high speed streams.
The geomagnetic field is expected to be unsettled with a chance for active periods for 16-17 June due to a coronal hole high speed stream. Quiet levels are expected for 18-24 June, followed by another increase to mostly unsettled levels with isolated active periods for 25-30 June due to another coronal hole high speed stream. Quiet levels are expected for 01-12 July.
