1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 15.02.2022 at 20:00 UTC was 114 sfu.
The background X-Ray flux is at the class B3.4 level.
The geomagnetic field was at quiet to unsettled levels on Feb 15.
AR2941 (N26W81) produced a M1.3 class solar flare on Feb. 15 at 18:15 (peak time) and a short radio blackout (R1) was observed. 
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at unsettled levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 380 km/s.
Solar Wind speed from STEREO A: 370 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 1 nT north

3. Solar Energetic Particle Events
Protons and electrons are quiet.

4. Coronal Holes
A recurrent coronal hole at the northern hemisphere (CH1062) will likely rotate across the central meridian on February 16. A coronal hole at the southern hemisphere (CH1063) will be in Earth facing position on Feb. 15-16.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on Feb. 16-18.
