Highlights of Solar and Geomagnetic Activity  04 - 10 May 2020

Solar activity was very low. Regions 2760 (S06, L=306, class/area Cro/020 on 29 Apr) and 2763 (N32, L=260, class/area Bxo/010 on 30 Apr) were both plage regions as they rotated off the west limb on 05 May and 08 May, respectively. 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. The peak flux was 240 pfu observed at 09/0420 UTC.

Geomagnetic field activity was mostly quiet with isolated unsettled periods observed on 06 and 10 May. Solar wind parameters were at nominal levels with solar wind speed ranging from 285-360 km/s. Total field ranged from 1-8 nT while the Bz component was between +6/-7 nT.

Forecast of Solar and Geomagnetic Activity 11 May - 06 June 2020

Solar activity is expected to be at very low levels on 11 May - 06 Jun.

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.

Geomagnetic field activity is expected to be mostly quiet. Unsettled levels are expected on 13-14 May and 18-19 May due to coronal hole high speed stream activity.
