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.

The solar wind speed (recorded by DSCOVR) varied between about 380 and 430 km/s in the past 24 hours, with current values around 405 km/s. The Interplanetary Magnetic Field (IMF) was directed mainly toward the Sun and its magnitude ranged between about 1 and 10 nT. Bz had excursions below -5 nT between 07:40 and 09:30 UT on February 22. On February 22, 23 and 24 the solar wind is expected to be at nominal levels, possibly with occasional periods of enhanced solar wind as the Earth comes close to the high speed stream associated with the negative polarity south polar coronal hole.

Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on February 22, 23 and 24, with a chance for active intervals (K Dourbes = 4) when the Earth comes close to the high speed stream associated with the negative polarity south polar coronal hole.
