1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7) measured on 22.10.2014 at 2300UTC was 216 sfu.
The background x-ray flux is at the class C1 level.
The geomagnetic field was quiet to active levels on October 22. 
The AR 2192 continuous to emerge solar flares and the most important was a X1.6  Oct 22 at 14:28 U.T. 
No obviously Earth directed CMEs were observed in LASCO and STEREO imagery.
GOES Hp is almost quiet with Kp=2.

2. Solar Wind Geomagnetic Activity
ACE: Solar wind speed now is 425 km/s.
STEREO A: Solar wind speed now is 520 km/s.
STEREO B: N/A.
The southward component of Bz now is 1.6 nT north.

3. Solar Energetic Particle Events
None. Protons and electrons are quiet.

4. Coronal Holes
A recurrent trans equatorial coronal hole (CH640) will be in an Earth facing position on October 19-22.

5. Geophysical Activity Forecast
Coronal Hole CH640 effecting the interplanetary space and the geomagnetic field is expected to reach quiet to unsettled levels on October 23-25.
