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) further decreased from about 475 to 415 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed mainly toward the Sun and its magnitude ranged between about 5 and 8 nT. Bz was never below -5 nT. On February 25, the solar wind is expected to be at nominal levels, with a chance for occasional periods of slightly enhanced solar wind. On February 26, an enhancement in the solar wind is expected, associated with a high speed stream from the negative polarity south polar coronal hole. A return to nominal solar wind values is expected on February 27.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected for February 25 and 27, with a chance for active intervals (K Dourbes = 4). Active levels (K Dourbes = 4) are possible on February 26, with a chance for minor storm intervals (K Dourbes = 5).
