1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 08.04.2015 at 20:00 UTC was 106 sfu.
The background X-Ray flux is at the class B2 level.
The geomagnetic field was at very quiet levels on April 8.
No obviously Earth directed CMEs were observed.
The Kp index now is at almost quiet levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar wind speed from ACE: 370 km/s.
Solar wind speed from STEREO A: --- km/s.
Solar wind speed from STEREO B: --- km/s.
The southward component of Bz is: 0.3 nT south.

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

4. Coronal Holes
A recurrent trans equatorial coronal hole (CH662) was in an Earth facing position on April 5. 
No geomagnetic disturbances have been associated with CH662 during previous rotations.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on April 9-10 and at quiet levels on April 11.
