*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2020 July 05 07:07UTC 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 04.07.2020 at 20:00 UTC was 70 sfu. The background X-Ray flux is at the class < A1 level. The geomagnetic field was at very quiet to unsettled levels on July 4. No obviously Earth directed CMEs were observed in available LASCO imagery. The Kp index now is at unsettled levels with Kp=3. 2. Solar Wind Geomagnetic Activity Solar Wind speed from ACE: 500 km/s. Solar Wind speed from STEREO A: 350 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 new and small coronal hole (CH966) in the northern hemisphere of the Solar disk will be in Earth facing position on July 2. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at quiet to unsettled levels on July 5 and at quiet levels on July 6-7.
