Highlights of Solar and Geomagnetic Activity 11 - 17 May 2020
Solar activity was very low. The solar disk was spotless. Beginning on 15 May, a rise in x-ray flux background was observed as two plage regions emerged on the ENE and ESE limbs, possibly the return of old Regions 2762 (N23, L=338) and 2761 (S18, L=332). No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels with a peak flux of 203 pfu observed at 16/0220 UTC.
Geomagnetic field activity was mostly quiet with an isolated unsettled period observed late on 12 May. Solar wind parameters were at nominal levels with solar wind speed ranging from 282-354 km/s while total field was between 1-8 nT.
Forecast of Solar and Geomagnetic Activity 18 May - 13 June 2020
Solar activity is expected to continue at very 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 to moderate levels for the outlook period (18 May- 13 Jun).
Geomagnetic field activity is expected to reach unsettled levels on 19-20 May due to weak coronal hole high speed stream activity (CH HSS). Mostly quiet conditions are expected for the rest of the period.
