*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2020 July 15 05:50UTC Prepared by the Athens Space Weather Forecasting Center *********************************************************************** 1. Solar activity Solar activity was increasing during the past 24 hours. Solar Flux (10.7 cm) measured on 14.07.2020 at 20:00 UTC was 69 sfu. The background X-Ray flux is at the class A2.1 level. The geomagnetic field was at very quiet to active levels on July 14. 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: 355 km/s. Solar Wind speed from STEREO A: 370 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 No obvious coronal holes are currently in the visible solar disk. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at quiet to unsettled levels on July 15 and at very quiet levels on July 16-17.
