1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 11.04.2023 at 20:00 UTC was 143 sfu.
The background X-Ray flux is at the class C1.4 level.
The geomagnetic field was at quiet to unsettled levels on April 11.
AR3272 erupted on April 11 at 10:16 peak time producing a M1.3 class solar flare and a short radioblackout of category R1. 
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: 368 km/s.
Solar Wind speed from STEREO A: 400 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 coronal hole (CH1140) at northern hemisphere will become Earth facing on April 07-08.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on April 12-13 and at quiet levels on April 14.
