1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 10.11.2018 at 20:00 UTC was 69 sfu.
The background X-Ray flux is at the class A2 level.
The geomagnetic field was at quiet to active levels on November 10.
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: 545 km/s.
Solar Wind speed from STEREO A: 290 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
A large coronal hole (CH893) was in Earth facing position on November 6-10.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels, with a chance for active intervals, on November 11-12 and at quiet levels on November 13.
