Highlights of Solar and Geomagnetic Activity 27 April - 03 May 2020
Solar activity was very low throughout the period. Four new-cycle sunspot groups were numbered this period, the most prominent of which was Region 2760 (S07, L=307, class/area=Cro/20 on 30 Apr). No significant solar flare activity was observed.
A filament eruption from the northern hemisphere midday on 27 Apr resulted in a very slow-moving CME. Modeling of the event suggested the CME may arrive at Earth on 02-03 May. A solar wind disturbance commensurate with the passage of a weak, slow-moving transient was detected on 03 May, however, the source of this disturbance is inconclusive at the time of this writing.
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 period.
Geomagnetic field activity was generally quiet and quiet to unsettled this period under a largely nominal solar wind environment. Isolated unsettled activity late on 03 May is thought to be associated with the passage of the 27 Apr CME.
Forecast of Solar and Geomagnetic Activity 04 May - 30 May 2020
Solar activity is expected to be very quiet throughout the outlook period.
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 throughout the outlook period.
Geomagnetic field activity is expected to be generally quiet or quiet-to-unsettled throughout the outlook period.
