1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 06.02.2022 at 20:00 UTC was 124 sfu.
The background X-Ray flux is at the class B5.4 level.
The geomagnetic field was at unsettled to active levels on Feb 06.
AR12939 produced a C3.1 class solar flare on Feb 06 at 13:40 (peak time). A partial halo CME observed after the C-class flare in C2/C3 coronographs. The CME is expected to reach Earth according EAM predictions on Feb 09 between 13:42 and 19:26.
No obviously Earth directed CMEs were observed in available LASCO imagery for Feb 03-05.
The Kp index now is at unsettled levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 479 km/s.
Solar Wind speed from STEREO A: 380 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 new equatorial coronal hole (CH1058) was in Earth facing position on Feb. 1-2. A new coronal hole (CH1059) on the southern hemisphere of the visible solar disk will be in Earth facing position on Feb. 5-6.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on Feb 07-08 and at unsettled to active levels on Feb 09.
