Highlights of Solar and Geomagnetic Activity 30 March - 05 April 2020

Solar activity was very low throughout the period. Region 2759 (N28, L=263, class/area Hrx/030 on the 02 Apr) formed on the disk on 31 Mar and produced a few B-class events early on 04 Apr. The region decayed to plage on 05 Apr. No Earth-directed CMEs were detected.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 01-04 Apr and the moderate levels on 30-31 Mar and 04-05 Apr. A maximum flux of 1,690 pfu was observed on 02 Apr at 1750 UTC.

Geomagnetic field activity was at unsettled to active levels on 30-31 Mar due to negative polarity CH HSS influence. The remainder of the period experienced quiet to unsettled levels with an isolated and active period observed late on 03 Apr.

Forecast of Solar and Geomagnetic Activity 06 April - 02 May 2020

Solar activity is expected to be very low 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 reach high levels on the 19-22 Apr and 29-30 Apr. Normal to moderate levels are expected to prevail throughout the  remainder of the outlook period.

Geomagnetic field activity is expected to reach unsettled to active levels on 10-11 Apr, 15-19 Apr and 26-27 Apr. This is due to negative polarity CH HSS influence. Generally quiet or quiet to unsettled conditions are expected to prevail throughout the remainder of the outlook period.
