1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 04.01.2016 at 20:00 UTC was 95 sfu.
The background X-Ray flux is at the class B2 level.
The geomagnetic field was at quiet levels on January 4.
The Jan. 2 CME which expected to reach Earth, finally did not. 
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: 380 km/s.
Solar Wind speed from STEREO A: 420 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 trans equatorial coronal hole (CH708) rotated across the central meridian on January 2-3.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at very quiet levels on Jan. 5 and at quiet to active on Jan. 6-7 due to coronal holes.

    Date         Estimated Geomagnetic Ap index
