INFO FROM SIDC - RWC BELGIUM 2019 Feb 20 12:30UTC

Solar activity was at very low levels. An A9.7 flare peaked at 04:24 UT and
was related to the eruption of the filament in former active region NOAA
2733 between 04 and 05 UT. This filament is reshaping itself and is
currently located near N10E00. Associated with this eruption was a narrow
and very slow moving (190 km/s) coronal mass ejection (CME) with a
potential earth-directed component (STEREO-A/COR2 imagery). A preliminary
estimate of the CME arrival near Earth is 26 February. The greater than 10
MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Solar wind speed showed a generally declining trend from 340 km/s at the
beginning of the period to 300 km/s at the end (DSCOVR). Bz ranged between
-3 and +2 nT, with solar wind proton density gradually increasing to its
current 10/cm3. The interplanetary magnetic field was mainly directed
towards the Sun (negative sector). Geomagnetic activity was at quiet
levels. 
 
Mostly quiet geomagnetic conditions are expected until the arrival of the
co-rotating interaction region and wind stream from the positive polarity
coronal hole later today or on 21 February. This may result in active
conditions, with a small chance on an isolated minor storming episode.
