*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2020 January 15 06:51UTC 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 14.01.2020 at 20:00 UTC was 72 sfu. The background X-Ray flux is at the class < A1 level. The geomagnetic field was at very quiet levels on January 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: 335 km/s. Solar Wind speed from STEREO A: --- km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 0 nT. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes A coronal hole (CH949) was in Earth facing position on January 10-11. Up to now this CH it was not a geoeffective one. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at very quiet levels, with a chance for unsettled and active intervals if CH949 be geoeffective, on January 15 and at very quiet levels on January 16-17.
