Highlights of Solar and Geomagnetic Activity
01 - 07 April 2019

Solar activity was very low throughout the period. Region 2737 (N12,
L=63, class/area-Cao/40 on 02 Apr) was inactive before decaying to
plage on 04 April. Region 2738 (N06, L=298, class/area-Hsx/300 on 07
Apr) produced low level B-class activity after rotating around the
east limb. No Earth-directed coronal mass ejections (CMEs) were
observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 05-07 April with moderate levels observed throughout
the remainder of the reporting period.

Geomagnetic field activity reached active levels on 01 and 03 April
with unsettled levels on 02, 04-06 April due to coronal hole
high-speed stream (CH HSS) influence. Quiet conditions were observed
on 07 April.

Forecast of Solar and Geomagnetic Activity
08 April - 04 May 2019

Solar activity is expected to be at very low to low levels
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 reach high levels on 08-12 April and 02-04 May with
normal to moderate levels expected throughout the remainder of the
outlook period.

Geomagnetic field activity is expected to reach unsettled levels on
24-25, 27-28, 30 April and 01-02 May. Quiet conditions are expected
throughout the remainder of the outlook period.
