1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 11.10.2015 at 20:00 UTC was 85 sfu.
The background X-Ray flux is at the class B2 level.
The geomagnetic field was at quiet to active levels on October 11.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at unsettled levels with Kp=3.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 470 km/s.
Solar Wind speed from STEREO A: 390 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component of Bz is: 1 nT south.

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

4. Coronal Holes
An extensive recurrent trans equatorial coronal hole (CH695) will be in a potentially geoeffective position on October 8-13.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on October 12-14.
