1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 01.12.2015 at 20:00 UTC was 96 sfu.
The background X-Ray flux is at the class B3 level.
The geomagnetic field was at quiet to unsettled levels on December 1.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at unsettled levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 410 km/s.
Solar Wind speed from STEREO A: 510 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component of Bz is: 2 nT north.

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

4. Coronal Holes
A recurrent southern hemisphere coronal hole (CH703) was in an Earth facing position on November 27-28. A recurrent northern hemisphere coronal hole (CH704) with a trans equatorial extension could rotate into an Earth facing position on December 2-6.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on Dec. 2-4.
