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 and ACE) gradually increased from about 405 to 550 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed mainly toward the Sun and its magnitude ranged between about 2 and 11 nT. Bz was variable and dived below -5 nT several times, with a minimum of about -8 nT. On February 23, 24 and 25 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 to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 2 and 5) were registered in the past 24 hours. Quiet to active geomagnetic levels (K Dourbes < 5) are expected for February 23, 24 and 25, with a chance for minor storm intervals (K Dourbes = 5) when the Earth comes close to the high speed stream associated with the negative polarity south polar coronal hole.
