1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 27.03.2020 at 20:00 UTC was 69 sfu.
The background X-Ray flux is at the class < A1 level.
The geomagnetic field was at quiet to unsettled levels on March 26. 
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: 375 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 north.

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

4. Coronal Holes
A new coronal hole (CH956) on the southern hemisphere of the visible solar disk, which is an extension of the southern polar coronal hole, was in Earth facing position on March 26-27.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at very quiet levels on March 28-29 and at quiet to unsettled levels on March 30 due to weak effects from CH956.
