1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 26.01.2023 at 20:00 UTC was 151 sfu.
The background X-Ray flux is at the class C5.0 level.
The geomagnetic field was at quiet to unsettled levels on January 26.
A M2.9 class solar flare erupted at 13:06 UT peak time from AR3190(N18W87). A radioblackout of category R1 was observed. 
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at quiet levels with Kp=1.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 521 km/s.
Solar Wind speed from STEREO A: - km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 1 nT south.

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

4. Coronal Holes
A coronal hole (CH1126) at southern hemisphere rotated across the central meridian on January 21.  A  coronal hole (CH1127) at northern hemisphere was Earth facing on January 24.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled on January 27-28 and at quiet levels on January 29.
