Here is this week's space weather and geophysical report, issued 2022 Feb 28 0132 UTC.

Highlights of Solar and Geomagnetic Activity 21 - 27 February 2022

Solar activity ranged from very low to low levels throughout the week. Regions 2954 (N17, L=118, class/area=Hsx/120 on 21 Feb) and 2955 (N14, L=107, class/area=Hsx/150 on 22 Feb) were the primary regions on the disk, but remained quiescent throughout the period. 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 high levels on 26 Feb, and was normal to moderate throughout the remainder of the period.

Geomagnetic field activity reached active levels on 21 Feb and Minor (G1) geomagnetic storm levels on 22 Feb due to the influence of a positive polarity CH HSS. Active conditions were once again observed on 27 Feb due to another geoeffective positive polarity CH HSS. Quiet and quiet to unsettled conditions were observed throughout the remainder of the week under a background solar wind environment.

Forecast of Solar and Geomagnetic Activity 28 February - 26 March 2022

Solar activity is expected to be very low with a chance for C-class flares 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 reach high levels on 28 Feb-08 Mar, 12-17 and 20-22 Mar in response to enhanced solar wind conditions associated with recurrent CH HSSs.

Geomagnetic field activity is expected to reach active levels on 28 Feb-01 Mar, 05-06, 11-12, and 19-21 Mar due to multiple recurrent CH HSSs. Quiet and quiet to unsettled field activity is expected to prevail throughout the remainder of the outlook period.
