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.

Forecast of Solar and Geomagnetic Activity 20 April - 16 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 be at mostly normal to moderate levels. 29-30 April will likely observed high levels in response to coronal hole influence.

Geomagnetic field activity is expected to be at quiet to active levels. Active levels are likely on 20 Apr, 27 Apr and 05 May; unsettled levels are likely on 21-23 Apr and 30 Apr. All enhancements in geomagnetic active are in response to multiple, recurrent CH HSSs. The remainder of the outlook period is expected to observed quiet conditions.
