#Weekly Highlights and Forecasts

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, 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
