#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 13 - 19 April 2020

Solar activity was very low throughout the reporting period. No sunspots were obseved on the visible disk and no Earth-directed CMEs were observed in available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the reporting period.

Geomagnetic field activity ranged from quiet to unsettled. Unsettled levels were observed on 14-15 Apr in response to several periods of prolonged southward Bz. The remainder of the reporting period observed quiet conditions.
