Highlights of Solar and Geomagnetic Activity 18 - 24 January 2021

Solar activity was at low and very levels for the highlight period. Other than 19-20 Jan, solar activity was very low with minimal B-level or below x-ray enhancements. Region 2797 (S17, L=335, class/area Cao/120 on 19 Jan) produced a C1 event on 19 Jan. Region
2798 (S16, L=331, class/area Cao/060 on 20 Jan) produced a C1.4/sf flare on 20 Jan. No Earth-directed CMEs were observed in available coronagraph imagery. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit remained at moderate levels throught the highlight period. 

Geomagnetic field activity was quiet throughout the period, except for 19-20 Jan. A single period of unsettled conditions was observed on both 19 and 20 Jan due to a solar sector boundary crossing (SSBC) as well as weak CH HSS activity. 

Forecast of Solar and Geomagnetic Activity - 25 January - 20 February 2021

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

Geomagnetic field activity is expected to reach unsettled levels on 25-26 Jan, 1-2 Feb, 7-8 Feb, and 20 Feb, due to recurrent CH HSS activity. Quiet levels are expected for the remainder of the outlook period.
