Weekly Propagation Summary (2019 Apr 22 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Apr 22 0049 UTC.

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.
