1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 30.01.2020 at 20:00 UTC was 74 sfu.
The background X-Ray flux is at the class A2 level.
The geomagnetic field was at almost quiet to active levels on January 30. 
No obviously Earth directed CMEs were observed in available LASCO imagery. 
The Kp index now is at active levels with Kp=4.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 475 km/s.
Solar Wind speed from STEREO A: --- km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 0 nT.

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

4. Coronal Holes
No obvious coronal holes are currently in the visible solar disk.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at almost quiet to active levels on January 31 due to effects from a shallow coronal hole and at almost quiet levels on February 1-2.
