Highlights of Solar and Geomagnetic Activity 07 - 13 June 2021
Solar activity was at low levels due to multiple C-class flares from an unnumbered region beyond the east limb. The largest C-class flare was a C3.7 at 09/0907 UTC from Region 2831 (N24, L=79, class/area Hrx/10 on 07 June). No Earth-directed CMEs were observed in coronagraph imagery. However, on 11-13 June coronagraph imagery was not available due to site maintenance at NASA. Availability of LASCO coronagraph imagery expected to resume on 15 June.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the highlight period.
Geomagnetic field activity was at quiet to unsettled levels on 08-11, and 13 June. Unsettled to active levels were reached on 07 June due to influences from the arrival of a recurrent coronal hole high-speed stream (CH HSS). Unsettled to active levels were reached on 13 June due to the combination of the likely arrival of a slow-moving CME from 06 June and CH HSS influences.
Forecast of Solar and Geomagnetic Activity 14 June - 10 July 2021
Solar activity is expected to be at very low to low levels with Region 2831 due to return to the visible disk from 21 June-05 July.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels on 20-22 June due to recurrent CH HSS influences. Normal to moderate levels are expected
for the remainder of the outlook period.
Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 17 June due to recurrent CH HSS influences. Unsettled to active levels are expected on 15, 16, and 18 June also due to recurrent CH HSS influences. Quiet to unsettled levels are expected for the remainder of the outlook period.
