1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 05.11.2016 at 20:00 UTC was 77 sfu.
The background X-Ray flux is at the class A6 level.
The geomagnetic field was at very quiet levels on November 5.
A filament erupted on Nov. 5 at 04:24 resulting on a CME which could produce a minor geomagnetic storm (G1) on Nov. 8-9.
The Kp index now is at quiet levels with Kp=1.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 330 km/s.
Solar Wind speed from STEREO A: 390 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 small southern hemisphere coronal hole (CH770) was in an Earth facing position on November 4. 
A recurrent trans equatorial coronal hole (CH771) could rotate across the central meridian on November 8-9.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at very quiet levels on November 6-7 and at quiet to minor storm levels, due to the CME of Nov. 5, on November 8.
