*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2018 November 02 06:56UTC 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 01.11.2018 at 20:00 UTC was 67 sfu. The background X-Ray flux is at the class A1 level. The geomagnetic field was at very quiet levels on November 1. No obviously Earth directed CMEs were observed in available LASCO imagery. The Kp index now is at quiet levels with Kp=1. 2. Solar Wind Geomagnetic Activity Solar Wind speed from ACE: 335 km/s. Solar Wind speed from STEREO A: 340 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 3 nT south. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes An equatorial coronal hole (CH892) was in Earth facing position on October 31 - November 1. A high speed stream of solar wind is expected to reach Earth on the first hours of November 3. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at very quiet levels on November 2 and at quiet to minor storm levels, with a chance for moderate storm intervals, on November 3-4 due to CH892 effects.
