Weekly Propagation Summary – 2020 Jul 06 16:10 UTC

Weekly Propagation Summary (2020 Jul 06 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Jul 06 0150 UTC.

Highlights of Solar and Geomagnetic Activity 29 June – 05 July 2020

Solar activity was very low. Region 2766 (N06 L=117, class/area Bxo/beta on 04 Jul) was the only active region on the visible disk. The region was in decay at the end of the reporting period.

Other activity included a DFS, approximately 18 degrees in length, which erupted in the SE quadrant beginning around 05/0630 UTC. Subsequent SOHO/LASCO C2 imagery showed the related CME signature after 05/1412 UTC. Analysis for an Earth-directed component is ongoing.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal background to moderate levels.

Geomagnetic field activity ranged from quiet to unsettled. Unsettled levels were observed on 01 Jul due to sustained southward Bz and on 04-05 Jul in response to a positive polarity CH HSS. The remainder of the summary period was at quiet levels under nominal solar wind conditions.

Forecast of Solar and Geomagnetic Activity 06 July – 01 August 2020

Solar activity is expected to be at very 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 be normal background to moderate levels throughout the outlook period.

Geomagnetic field activity is expected to be at quiet to unsettled levels. A recurrent positive polarity CH HSS is expected to cause isolated unsettled levels on 06 Jul and again on 31 Jul – 01 Aug. The remainder of the outlook period is expected to be at quiet levels. Analysis and modeling of the 5 Jul CME is not complete and the presence of an Earth-directed component is possible.
