There are no sunspot regions on the visible hemisphere of the Sun and flaring level is very low. The chance for a C flare in the next 24 hours is estimated at 5%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed measured by DSCOVR decreased from about 570 to 440 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed towards the Sun and its magnitude varied between about 1 and 8 nT, with current values around 3 nT. Bz was variable and never below -5 nT. Solar wind is expected to decrease further in the next 24 hours as coronal hole high speed stream influence wanes.

Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 1 and 4) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on February 20, 21 and 22, with a chance for active conditions (K Dourbes = 4).
