1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 30.01.2019 at 20:00 UTC was 74 sfu.
The background X-Ray flux is at the class A5 level.
The geomagnetic field was at very quiet levels on January 30.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at very quiet levels with Kp=0.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 330 km/s.
Solar Wind speed from STEREO A: 380 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 new equatorial coronal hole (CH905) will be in Earth facing position on January 26-31.
A high speed stream of solar wind is expected to reach Earth on the second half of January 31.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at very quiet to active levels, with a chance for minor storm intervals, on January 31 - February 2 due to CH905 effects.
