Highlights of Solar and Geomagnetic Activity 28 May - 03 June 2012
Solar activity was at very low to moderate levels during the period. Very low levels were observed from 28 - 29 May. An increase to low levels was observed from 30 May - 02 June as Region 1493 (N15, L=209, class/area Dso/170 01 June) and Region 1496 (N16, L=199 class/area Cso/120 on 01 June) rotated onto the visible disk. Another increase to moderate levels was observed on 03 June as Region 1496 produced an M3 x-ray flare at 03/1755 UTC. Associated with this event were both a Type II radio sweep (estimated shock speed of 1077 km/s) signature and CME supporting imagery from the LASCO C2 imager. After analysis, this CME was determined to not be Earth directed. Region 1493 was the most active region during the period producing 8 C-class x-ray events.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 28 - 29 May and then decreased to moderate to normal levels for the remainder of the period.
Geomagnetic field activity was at quiet to minor storm levels during the period. Quiet conditions were observed from 28 - 29 May. Late on 29 May, solar wind speeds, as measured by the ACE spacecraft, increased from 350 km/s to around 450 km/s. Solar wind speeds remained elevated till late on 31 May. In conjunction with these elevated solar winds, quiet to unsettled levels were observed from 30 - 31 May with isolated active and minor storm levels at high latitudes. A return to quiet levels was observed from 01 - 02 June. Late on 02 June, an isolated active period was observed due to prolonged negative IMF Bz measured by the ACE spacecraft. On 03 June, an increase from quiet to minor storm levels with major storm periods observed at high latitudes was observed. This increase in activity was associated with a continuation of sustained negative IMF Bz from 02 June.
Forecast of Solar and Geomagnetic Activity
04 June - 30 June 2012
Solar activity is expected to be at low levels with a chance for M-class activity from 04 - 15 June.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels during 04 - 05 June, 13 - 19 June, and 26 - 30 June. High levels are expected during 06 - 12 June, and 20 - 25 June.
Geomagnetic field activity is expected to be at active levels with a chance for minor storm levels on 04 - 05 June as a coronal hole high speed stream (CH HSS) becomes geoeffective. Quiet to active levels are expected on 06 June as CH HSS effects persist. A decrease to quiet to unsettled levels is expected on 07 - 08 June as the CH HSS wanes. Predominantly quiet levels are expected from 09 - 17 June.
Quiet to active levels are expected from 18 - 20 June as another CH HSS becomes geoeffective. A return to mostly quiet levels is expected for the remainder of the period.
