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.
