1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 25.11.2020 at 20:00 UTC was 104 sfu.
The background X-Ray flux is at the class B6.1 level.
The geomagnetic field was at quiet to unsettled levels on November 25.
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: 390 km/s.
Solar Wind speed from STEREO A: 375 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 1 nT north.

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

4. Coronal Holes
A coronal hole (CH980) on the northern hemisphere of the visible solar disk was in Earth facing position on Nov. 19-20.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at almost quiet levels, with a chance for unsettled intervals, on Nov. 26-27 and at quiet levels on Nov. 28.
