Here is this week's space weather and geophysical report, issued 2019 Feb 25 0822 UTC.

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.
