Highlights of Solar and Geomagnetic Activity
18 - 24 February 2019

Solar activity was very low. A DSF centered near N19W38 was observed
lifting off after 23/2332 UTC. A subsequent CME signature was first
observed in LASCO C2 imagery at 24/0125 UTC. However, after
forecaster analysis and WSA/Enlil modeling, the CME was determined
to be off the Sun-Earth line.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
moderate levels on 18-20 Feb. Normal levels were observed during the
rest of the summary period.

Geomagnetic field activity reached active levels on 21 Feb due to CH
HSS influences. The remainder of the period was at mostly quiet
levels.

Forecast of Solar and Geomagnetic Activity
25 February - 23 March 2019

Solar activity is expected to remain very low for the forecast
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 to high levels on 25 Feb - 10 Mar, and 13
Mar due to recurrent CH HSS activity. Normal to moderate levels are
expected for the remainder of the outlook period.

Geomagnetic field activity is expected to be at G1 (Minor) storm
levels on 27-28 Feb due to recurrent CH HSS activity. The remainder
of the period is expected to be mostly quiet to unsettled.
