1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 27.10.2022 at 20:00 UTC was 122 sfu.
The background X-Ray flux is at the class B6.0 level.
The geomagnetic field was at quiet to unsettled levels on October 27.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at quiet levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 423 km/s.
The southward component Bz is: 2 nT south.

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

4. Coronal Holes
A recurrent coronal hole (CH1108) at northern hemisphere will rotate into an Earth facing position on October 24-25. A new recurrent equatorial coronal hole (CH1109) will rotate across the central meridian on October 26-28.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels with isolated active periods on October 28 due to the effect of the coronal hole (CH1108) high speed stream, at quiet to minor storm (G1) levels on October 29-30 due to the effect of the coronal hole (CH1109).
