Weekly Propagation Summary – 2018 Jun 04 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Jun 04 0252 UTC.
Highlights of Solar and Geomagnetic Activity 28 May – 03 June 2018
Solar activity reached low levels during the period due to an isolated C-class event, a C2/Sf flare from Region 2712 (N15, L=176, class/area Csi/80 on 28 May). 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 moderate levels on 28-31 May and high levels on 01-03 June due to influence from a negative polarity coronal hole high-speed stream (CH HSS). The peak flux observed was 28,659 pfu at 02/1900 UTC.
Geomagnetic field activity reached G1 (Minor) storm levels on 01 June and active levels on 31 May and 02 June due to influence from a negative polarity CH HSS. Quiet to unsettled conditions were observed throughout the remainder of the week.
Forecast of Solar and Geomagnetic Activity 04 June – 30 June 2018
Solar activity is expected to be very low throughout the period, with a slight chance for isolated C-class events on 04-05 and 18-30 June, due to flare potential from Region 2712.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach very high levels on 05-07 June with high levels expected on 04, 08-13, and 28-30 June. Moderate flux levels are expected for the remainder of the outlook period.
Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 28 June, with active levels on 27 and 29 June, due to influence from a recurrent, negative polarity CH HSS. Unsettled levels are expected on 04-05, 13, 19, and 30 June. Quiet conditions are expected during the remainder of the outlook period.

HOW CAN YOU HELP?
I am working on launching a YouTube channel overhaul, that includes series of videos about space weather, radio signal propagation, and more.
Additionally, I am working on improving the educational efforts via the email, Facebook, YouTube, Tumblr, and other activities.
