1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 30.09.2022 at 20:00 UTC was 137 sfu.
The background X-Ray flux is at the class C2.0 level.
The geomagnetic field was at quiet to active levels on September 30.
AR3112 produced three M-class flares on September 30 and the biggest is the M2.9 solar flare at 16:22 peak time.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at quiet levels with Kp=0.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 410 km/s.
Solar Wind speed from STEREO A: - km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 1 nT south.

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

4. Coronal Holes
A recurrent equatorial coronal hole (CH1103) was Earth facing on September 27-30.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm (G1) levels on October 01-02 due to effects of coronal hole (CH1103) high speed stream and at unsettled to active levels on October 03.
