*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2018 November 14 05:47UTC Prepared by the Athens Space Weather Forecasting Center *********************************************************************** 1. Solar activity Solar activity was decreasing stable during the past 24 hours. Solar Flux (10.7 cm) measured on 13.11.2018 at 20:00 UTC was 67 sfu. The background X-Ray flux is at the class A4 level. The geomagnetic field was at very quiet levels on November 13. 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: 420 km/s. Solar Wind speed from STEREO A: 370 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 3 nT north. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes A large coronal hole (CH893) was in Earth facing position on November 6-10. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at very quiet levels on November 14-16.
