Solar activity was relatively quiet over the last 24 hours besides the number of bipolar sunspot groups visible on the disc, and the continuously growing Catania sunspot group 17 (NOAA-AR 2936). Several C-class flares were recorded and produced by the sunspot group 17. The other sunspot groups did not show any significant flaring activity. Solar activity is expected to become more active due to the growing sunspot group 17 with more C-class flares and possibly also M-class flare in the next 24 hours.

No Earth directed Coronal Mass Ejection (CME) has been detected in the available coronagraph imagery over the last 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain at nominal levels in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below the threshold in the next 24 hours. The greater than 2 MeV electron fluence dropped to nominal levels in the past 24 hours and is expected remained at nominal levels in the next 24 hours.

The solar wind parameters measured in the Earth environment (by DSCOVR) remained enhanced due to the effects of the solar high-speed stream, first connected to the Coronal Hole (positive magnetic polarity) that crossed the central meridian on January 21, then followed by the Coronal Hole that crossed on January 26 (also positive magnetic polarity). The solar wind speed reached 539 km/s, the interplanetary magnetic field values were ranging between 5 nT and 9 nT, and its southward Bz-component fluctuated between -7.7 nT and 6.3 nT. The solar wind conditions are expected to remain slightly enhanced for the flowing 1-2 days.

Geomagnetic conditions were quiet to unsettled (K_Bel 1-3) and at planetary levels reached active condition (NOAA-Kp 4) in response to the solar wind enhancement. Mainly quiet to unsettled geomagnetic conditions are expected with possible short periods of active conditions.
