*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2020 January 30 06:37UTC 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 29.01.2020 at 20:00 UTC was 74 sfu. The background X-Ray flux is at the class A1 level. The geomagnetic field was at quiet to unsettled levels on January 29. 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: 415 km/s. Solar Wind speed from STEREO A: --- km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 1 nT south. 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, with a chance for active intervals, on January 30 due to effects from a shallow coronal hole and at quiet levels on January 31 - February 1.
