Highlights of Solar and Geomagnetic Activity 02 - 08 March 2020

Solar activity was very low. A new spot group emerged in the SE quadrant on 07 Mar and was numbered Region 2758 (S29, L=229, class/area Cro/020 on 08 Mar). No Earth-directed CMEs were observed during the reporting period.

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 923 pfu observed at 02/1455 UTC.

Geomagnetic field activity ranged from quiet to unsettled levels. Solar wind parameters were slightly enhanced midday on 02 Mar as solar wind speed reached a peak of 488 km/s at 02/1318 UTC, are likely due to a connection with an extension off the southern crown, polar coronal hole high speed stream (CH HSS). Solar wind speed gradually diminished to nominal levels by 04 Mar. The geomagnetic field responded with mostly quiet conditions with an isolated unsettled period observed on 04 Mar.

Forecast of Solar and Geomagnetic Activity 09 March - 04 April 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 reach high levels on 19-21 Mar due to CH HSS influence.

Geomagnetic field activity is expected to be reach unsettled levels on 10-11, 18-20, 27-28 Mar and active levels on 19 and 27 Mar due to recurrent CH HSS effects. Mostly quiet levels are expected for the remainder of the outlook period.
