1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 31.10.2022 at 20:00 UTC was 128 sfu.
The background X-Ray flux is at the class B5.0 level.
The geomagnetic field was at quiet to unsettled levels on October 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: 468 km/s.
Solar Wind speed from STEREO A: 400 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 4 nT south.

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

4. Coronal Holes
A recurrent equatorial coronal hole (CH1109) rotated across the central meridian on October 26-28. A recurrent coronal hole (CH1110) at northern hemisphere rotated across the central meridian on October 28-30. A new equatorial coronal hole (CH1111) will become Earth facing on November 01.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled with isolated active levels on November 01 due to the effect of coronal hole high speed stream and at quiet to unsettled levels on November 02-03.
