1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 31.05.2016 at 20:00 UTC was 87 sfu.
The background X-Ray flux is at the class B1 level.
The geomagnetic field was at quiet to unsettled levels on May 31.
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: 460 km/s.
Solar Wind speed from STEREO A: 510 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
A recurrent trans equatorial coronal hole (CH738) will likely rotate into an Earth facing position on June 1-3.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on June 1-3.
