1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 06.01.2020 at 20:00 UTC was 71 sfu.
The background X-Ray flux is at the class A2 level.
The geomagnetic field was at very quiet to active levels on January 6.
No obviously Earth directed CMEs were observed in available LASCO imagery. 
The Kp index now is at almost quiet levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 450 km/s.
Solar Wind speed from STEREO A: --- km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 2 nT north.

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

4. Coronal Holes
A new coronal hole (CH948) was in Earth facing position in the southern hemisphere of the visible solar disk on January 5. A high speed stream of solar wind from this CH is expected to reach Earth on the first half of January 8.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at almost quiet levels on January 7 and at quiet to active levels on January 8-9 due to CH948 effects.
