Here is this week’s space weather and geophysical report, issued 2020 Feb 24 0149 UTC.

Highlights of Solar and Geomagnetic Activity 17 - 23 February 2020

Solar activity was very low. No active regions with sunspots were observed and no apparent earth-directed CMEs were detected this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 17-19 Feb and high levels on 20-23 Feb.

Geomagnetic field activity reached active levels on 18 Feb and active to G1 (Minor) geomagnetic storm levels on 19 Feb. The enhanced geomagnetic field activity on 18-19 Feb were attributed to the passage of a transient solar wind feature. Active conditions were once again observed on 21 Feb due to negative polarity CH HSS influence. Generally quiet or quiet to unsettled conditions were observed throughout the remainder of the week.

Forecast of Solar and Geomagnetic Activity 24 February - 21 March 2020

Solar activity is expected to be very low 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 24 Feb-01 Mar, 05-09 Mar, and 19-21 Mar. Normal or normal to moderate levels are expected to prevail throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 26 Feb, 04-05 Mar, and 19 Mar due to the infuences of multiple recurrent CH HSSs. Generally quiet or quiet to unsettled conditions are expected to prevail throughout the rest of the outlook period under a nominal solar wind regime.
