*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2020 May 04 05:41UTC 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 03.05.2020 at 20:00 UTC was 69 sfu. The background X-Ray flux is at the class < A1 level. The geomagnetic field was at quiet to unsettled levels on May 3. No obviously Earth directed CMEs were observed in available LASCO imagery. The Kp index now is at almost quiet levels with Kp=2. 2. Solar Wind Geomagnetic Activity Solar Wind speed from ACE: 330 km/s. Solar Wind speed from STEREO A: 470 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 4 nT north. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes A new small equatorial coronal hole was in Earth facing position on May 1. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at almost quiet levels on May 4 and at quiet to unsettled levels, with a chance for active intervals, on May 5-6.
