Here is this week’s space weather and geophysical report, issued 2019 Apr 01 0125 UTC.

Highlights of Solar and Geomagnetic Activity 25 - 31 March 2019

Solar activity was very low throughout the period. Region 2736 (N08, L=284, class/area-Eki/420 on 22 Mar) produced low level B-class flare activity after its rotation around the west limb. Region 2737 (N12, L=059, class/area-Bxo/10 on 31 Mar) emerged on the disk but was inactive. No Earth-directed coronal mass ejections (CME) were observed.

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity reached active levels on 31 March and unsettled levels on 26-28 March due to influence from multiple, negative polarity coronal hole high-speed streams (CH HSS). Quiet conditions were observed on 25, 29-30 March.

Forecast of Solar and Geomagnetic Activity 01 April - 27 April 2019

Solar activity is expected to be very low on 01-05 and 20-27 April. Low levels are expected between 06-19 April due to the return of Region 2736.

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 01-07 April with normal to moderate levels expected throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 12 April due to influence from a recurrent, negative-polarity CH HSS. Quiet to unsettled levels are expected throughout the remainder of the outlook period.
