1. Solar activity
Solar activity was almost stable during the past 24 hours.
Solar Flux (10.7 cm) measured on 05.03.2017 at 20:00 UTC was 73 sfu.
The background X-Ray flux is at the class Α6 level.
The geomagnetic field was at unsettled to active levels on March 5.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at almost unsettled levels with Kp=3.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 640 km/s.
Solar Wind speed from STEREO A: 380 km/s.
Solar Wind speed from STEREO B: --- km/s.

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

4. Coronal Holes
A coronal hole (CH792) on the southern hemisphere was in Earth facing position on Feb. 25-27.
The high speed stream from this CH reached Earth on the first half of Mar. 1.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels on March 6 and at quiet levels on Mar. 7-8.
