1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 04.12.2022 at 20:00 UTC was 144 sfu.
The background X-Ray flux is at the class C2.O level.
The geomagnetic field was at quiet to active levels on December 04.
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: 400 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 3 nT south.

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

4. Coronal Holes
A recurrent equatorial coronal hole (CH1118) will likely rotate across the central meridian on December 04-05.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled leves on December 05, at quiet levels on December 06 and at quiet to active levels on December 07 due to effects from coronal holes (CH1118).
