Highlights of Solar and Geomagnetic Activity 11 - 17 February 2019
Solar activity was at very low levels. There were no numbered spot regions. No Earth-directed CMEs were observed in coronagraph imagery. No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 11 and 14 Feb, with a maximum flux of 1,890 pfu at 11/1445 UTC. Normal to moderate levels were observed on the remaining days. 

Geomagnetic field activity was at mostly quiet to unsettled levels. Active levels were observed on 13 Feb. 

Forecast of Solar and Geomagnetic Activity 18 February - 16 March 2019
Solar activity is expected to be very low levels throughout the forecast period. No notable regions are due to return to the visible disk. 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 21 Feb - 10 Mar and 13 Mar. Normal to moderate levels are expected for 18-20 Feb, 11-12 Mar, and 14-16 Mar. 

Geomagnetic field activity is expected to be at G1 (Minor) geomagnetic storming levels on 28 Feb - 01 Mar as the result of recurrent, negative polarity CH HSS influences. Mostly quiet to unsettled levels are expected for the rest of the outlook period.
