Weekly Propagation Summary – 2020 Jul 13 16:10 UTC

Weekly Propagation Summary (2020 Jul 13 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Jul 13 0246 UTC.

Highlights of Solar and Geomagnetic Activity 06 – 12 July 2020

Solar activity was very low throughout the summary period. Region 2766 (N05, L=122, class/area Bxo/010 on 10 Jul) was the only spotted region and decayed to plage by 11 Jul.

A filament eruption near S29W18 produced a faint, slow-moving CME signature in LASCO/SOHO C2 imagery beginning at 09/0724 UTC. Analysis and modeling of the event suggested a possible glancing blow from the CME around 14 Jul.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the summary period.

Geomagnetic field activity was quiet. No significant periods of southward Bz were observed.

Forecast of Solar and Geomagnetic Activity 13 July – 08 August 2020

Solar activity is expected to be very low over the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to continue at normal to moderate levels.

Geomagnetic field activity is expected to range from quiet to active levels. Unsettled conditions are likely on 13 Jul and 31 Jul – 01 Aug in response to coronal hole influence. Active conditions are likely on 14 Jul due to the anticipated arrival of a slow-moving transient that left the Sun on 09 Jul. The remainder of the outlook period is expected to be at quiet levels under a nominal solar wind environment.
