Here is this week's space weather and geophysical report, issued 2020 Nov 23 0446 UTC.

Highlights of Solar and Geomagnetic Activity 16 - 22 November 2020

Solar activity was at very low to low levels. Region 2785 (S23, L=359, class/area, Hsx/060 on 22 Nov) produced an impulsive C3/Sf flare at 22/1731 UTC, the largest of the period, from the E limb. Shortly after, the region produced a 160 sfu tenflare at 22/1943 UTC. Multiple CME signatures were observed in coronagraph imagery that appear to have originated near the region; however, given the proximity to the limb they are not likely to have an Earth-directed component.

Region 2783 (S23, L=072, class/area, Hsx/080 on 21 Nov) was mostly stable through the week but did produce a C1/1f flare at 20/1703 UTC. Some coronal dimming was observed around the region between 21/1600-1800 UTC and may be associated with a slow-moving CME signature seen in LASCO SOHO/C2 imagery after 21/2236 UTC. Analysis and modeling of the event is ongoing.

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 period.

Geomagnetic field activity ranged from quiet to G1 (Minor) geomagnetic storm levels. Quiet levels were observed over 16-19 Nov. A period of sustained southward Bz caused unsettled levels on 20 Nov. The onset of influence from a positive polarity CH HSS produced active conditions on 21 Nov and peaked with an isolated period of G1 (Minor) geomagnetic storm conditions on 22 Nov. Solar wind speeds increased to a peak between 600-650 km/s early on 22 Nov and gradually declined after. Total magnetic field strength peaked earlier with 12 nT observed at 21/2212 UTC and slowly declined to below 5 nT by the end of the reporting period. The Bz component reached a maximum southward deflection of -10 nT at 21/2212 UTC.

Forecast of Solar and Geomagnetic Activity 23 November - 19 December 2020

Solar activity is likely to be at low levels with a slight chance of R1 (Minor) radio blackouts from 23 Nov to 06 Dec. Very low levels are expected for the remainder of the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to range from normal to high levels. High levels are expected on 23-28 Nov and normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to at quiet to G1 (minor) geomagnetic storm levels. G1 conditions are likely on 19 Dec; active conditions are likely on 23 Nov, 25 Nov and 18 Dec; unsettled conditions are likely on 24 Nov, 26 Nov and 03-04 Dec. All increases in geomagnetic activity are expected due to multiple, recurrent CH HSSs. The remainder of outlook period is expected to be at quiet levels.
