1. Solar activity
Solar activity was decreasing stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 18.03.2022 at 20:00 UTC was 98 sfu.
The background X-Ray flux is at the class A0.0 level.
The geomagnetic field was at quiet to unsettled levels on Mar. 18.
A filament eruption began near AR 12967 around at 12:35 on Mar. 16 and was the source of a partial halo CME. The arrival of this CME to the Earth is possible between Mar. 19 17:13UT and Mar. 20 08:21UT according EAM forecasts.
No obviously Earth directed CMEs were observed in available LASCO imagery on Mar. 14-15.
The Kp index now is quiet levels with Kp=1.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 300 km/s.
Solar Wind speed from STEREO A: 350 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 3 nT south.

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

4. Coronal Holes
No obvious coronal holes are currently in the visible solar disk.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on Mar. 19 and at quiet to active levels on Mar. 20-21 due to the arrival of the CME.
