*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2018 November 26 08:39UTC 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 25.11.2018 at 20:00 UTC was 70 sfu. The background X-Ray flux is at the class A3 level. The geomagnetic field was at very quiet levels on November 25. No obviously Earth directed CMEs were observed in available LASCO imagery. The Kp index now is at very quiet levels with Kp=0. 2. Solar Wind Geomagnetic Activity Solar Wind speed from ACE: 320 km/s. Solar Wind speed from STEREO A: 390 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 2 nT north. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes Another equatorial coronal hole (CH897) will be in Earth facing position on November 26-27. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at quiet levels, with a chance for unsettled intervals, on November 26-27 and at very quiet levels on November 28.
