INFO FROM SIDC - RWC BELGIUM 2019 Feb 18 12:30UTC

Solar activity was at very low levels. The Sun was spotless. A 10-degrees
long filament in a spotless active region (former sunspot group NOAA 2733)
is currently located at N10E30. No coronal mass ejections were observed
over the last 24 hours. The greater than 10 MeV proton flux was at nominal
values. A diffuse and patchy positive polarity equatorial coronal hole (CH)
finished its transit of the central meridian yesterday 17 February.

Solar activity is expected to remain at very low levels.

Solar wind parameters were indicative of a small disturbance starting on 17
February around 15 UT. Wind speed varied mostly between 340 and 370 km/s
(DSCOVR). Bz ranged between -6 and +6 nT, with a 5-hour stretch of Bz
values near -5 nT centered around 00UT. The direction of the interplanetary
magnetic field (phi angle) was variable. Quiet to unsettled geomagnetic
conditions were observed. 
 
Quiet to unsettled geomagnetic conditions are expected to continue, until
the arrival of the co-rotating interaction region and wind stream from the
positive polarity coronal hole on 19 or 20 February. This may result in
active conditions, with a small chance on an isolated minor storming
episode.
