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.
