Highlights of Solar and Geomagnetic Activity
15 - 21 April 2019
Solar activity was very low throughout the period. Region 2738 (N06,
L=301, class/area-Hhx/400 on 17 Apr) produced several B-class events
including a B8 flare at 20/0050 UTC. Region 2739 (N05, L=258,
class/area-Cro/20 on 18 Apr) was inactive and stable during its
migration across the solar disk. 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 15 April with moderate levels observed throughout the
remainder of the reporting period.
Geomagnetic field activity reached unsettled levels on 15-16 April
due to coronal hole high-speed stream (CH HSS) influence. Quiet
conditions were observed throughout the remainder of the reporting
period.
Forecast of Solar and Geomagnetic Activity
22 April - 18 May 2019
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 reach high levels on 02-12 May with normal to moderate
levels expected throughout the remainder of the outlook period.
Geomagnetic field activity is expected to reach active levels on 27
April and 01-02, 07 May in response to several recurrent,
negative-polarity CH HSSs. Quiet to unsettled levels are expected
throughout the remainder of the outlook period.
