1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 23.06.2022 at 20:00 UTC was 129 sfu.
The background X-Ray flux is at the class B5.3 level.
The geomagnetic field was at unsettled levels on June 23.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at unsettled levels with Kp=3.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 442 km/s.
Solar Wind speed from STEREO A: - km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 5 nT north.

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

4. Coronal Holes
A coronal hole (CH1083) at northern hemisphere was in an Earth facing position on June 21-22. A coronal hole (CH1084) at southern hemisphere rotated across the central meridian on June 22-23. A equatorial coronal hole (CH1085) was in an Earth facing on June 22.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on June 24 and at quiet to active levels on June 25-26 due to the effects of coronal hole (CH1085).
