Highlights of Solar and Geomagnetic Activity
03 - 09 May 2010
Solar activity ranged from very low to moderate levels during the period. Activity was at very low levels on 03 May with occasional low-level B-class flares. Two faint, slow CME’s were observed during 04-05 May from Region 1066 (S26, L=207, class/area Cro/020 on 03 May). Both CME’s appeared to be Earth-directed. Activity increased to low levels on 04 May due to a C3/Sf flare at 04/1624 UTC from Region 1069 (N42, L=225, class/area Dai/170 on 05 May). Region 1069 emerged rapidly on 04 May as a beta-gamma magnetic structure. Activity increased to moderate levels on 05 May by virtue of an isolated M1/Sf flare at 05/1719 UTC from Region 1069. Activity decreased to very low levels on 06 May as Region 1069 gradually decreased in area, but maintained its magnetic complexity. Activity then returned to low levels during 07 - 09 May due to isolated B- and C-class flares from Region 1069, the largest of which was a C9/1f at 08/0459 UTC.
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.
Geomagnetic field activity ranged from quiet to major storm levels during the period. Activity on 03 May reached unsettled to minor storm levels with a brief major storm period at high latitudes as the coronal hole high-speed stream (CH HSS) effects from 02 May continued. Activity continued to gradually decrease during the remainder of the period as the CH HSS gradually subsided. Mostly quiet conditions were observed from 08 to 09 May.
Forecast of Solar and Geomagnetic Activity
12 May - 07 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 high flux levels on 12 May and at moderate levels from 13-15 May. Normal background levels are expected to prevail through 29 May. On 30 May, electron flux is expected to increase to high levels and remain high for the remainder of the period.
Geomagnetic field activity is expected to be at quiet to unsettled levels with isolated active periods from 12-16 May as effects of several CH HSS’s become geoeffective. Quiet conditions are expected from 17-19 May. Quiet to unsettled levels are expected for 20-21 May due to a recurrent CH HSS. Quiet levels are expected to return from 22 -28 May. Unsettled to active with isolated minor storm periods are expected for 29-31 May due to a recurrent CH HSS. Activity is expected to decrease to quiet to unsettled levels from 01-03 June as effects from the CH HSS subside. Quiet levels are expected from 04-06 June. Quiet to unsettled levels are expected on 07 June as another CH HSS becomes geoeffective.
