*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2018 June 06 06:33UTC Prepared by the Athens Space Weather Forecasting Center *********************************************************************** 1. Solar activity Solar activity was almost stable during the past 24 hours. Solar Flux (10.7 cm) measured on 05.06.2018 at 20:00 UTC was 71 sfu. The background X-Ray flux is at the class A5 level. The geomagnetic field was at almost quiet levels on June 05. 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: 430 km/s. Solar Wind speed from STEREO A: 440 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 0 nT. 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 very quiet levels on June 06-08.
