1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 10.04.2017 at 20:00 UTC was 74 sfu.
The background X-Ray flux is at the class A4 level.
The geomagnetic field was at very quiet levels on April 10. 
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at very quiet levels with Kp=1.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 400 km/s.
Solar Wind speed from STEREO A: 510 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 0 nT.

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

4. Coronal Holes
A new coronal hole (CH800) which is an extension of the northern polar coronal hole was in Earth facing position on April 6. A high speed stream from this CH finally reached Earth on the first hours of April 8.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at very quiet levels on April 11-13.
