Here is this week’s space weather and geophysical report, issued 2019 Apr 15 0125 UTC.

Highlights of Solar and Geomagnetic Activity 08 - 14 April 2019

Solar activity was very low throughout the period. Region 2738 (N06, L=297, class/area Cho/300 on 12 Apr) produced numerous B-class flare activity and low frequency radio burst activity. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels thoughout the period.

Geomagnetic field activity was at quiet to unsettled levels on 08-13 April due to negative polarity CH HSS influence. Isolated active levels were observed early on 08-10 April. Quiet levels were observed on 14 April.

Forecast of Solar and Geomagnetic Activity 15 April - 11 May 2019

Solar activity is expected to be at predominately very low levels throughout the outlook period. A slight chance for low level activity is possible through 24 April from Region 2738 and again from 04-11 May upon the return of old Region 2738 (N06, L=297).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels from 15-18 April and again from 02-11 May due to CH HSS influence. Normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach unsettled levels on 24-25, 27-28 and 30 April and 01-02 and 05-07 May, all due to negative polarity CH HSS influence. Quiet conditions are expected throughout the remainder of the outlook period.
