1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 01.08.2020 at 20:00 UTC was 72 sfu.
The background X-Ray flux is at the class A3.5 level.
The geomagnetic field was at very quiet levels on July 31.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at very quiet levels with Kp=0.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 370 km/s.
Solar Wind speed from STEREO A: 380 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 6 nT north.

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

4. Coronal Holes
A new coronal hole (CH969) on the northern hemisphere of the visible solar disk was in Earth facing position on July 29-31.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels, with a chance for active intervals, on August 02-04 due to weak effects from CH969.
