1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 01.04.2022 at 20:00 UTC was 147 sfu.
The background X-Ray flux is at the class C1.8 level.
The geomagnetic field was at unsettled to active levels on Apr. 01.
AR2975 (N13W48) produced a M9.6 class solar flare on Mar. 31 at 18:35 (peak time) and a short radio blackout (R1) was observed. 
AR2975 produced a Χ1.3 class solar flare on Mar. 30 at 17:30 (peak time). The X-class solar flare associated with a halo CME which is expecting to reach Earth according EAM predictions on Apr. 2 between 06:36 and 13:14.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at minor storm levels (G1)  with Kp=5.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 539 km/s.
Solar Wind speed from STEREO A: 400 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 2 nT south.

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

4. Coronal Holes
A coronal hole (CH1071) at southern hemisphere rotated across the central meridian on Mar. 30-31.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at unsettled to minor storm levels on Apr. 02-03 due to the effects of CMEs and at quiet to unsettled levels on Apr. 04.
