*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2019 June 30 05:31UTC Prepared by the Athens Space Weather Forecasting Center *********************************************************************** 1. Solar activity Solar activity was decreasing stable during the past 24 hours. Solar Flux (10.7 cm) measured on 29.06.2019 at 20:00 UTC was 68 sfu. The background X-Ray flux is at the class A7 level. The geomagnetic field was at very quiet levels on June 29. 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: 310 km/s. Solar Wind speed from STEREO A: 400 km/s. Solar Wind speed from STEREO B: --- km/s. The southward component Bz is: 1 nT north. 3. Solar Energetic Particle Events Protons and electrons are quiet. 4. Coronal Holes A new equatorial coronal hole (CH927) will be in Earth facing position on July 1. 5. Geophysical Activity Forecast The geomagnetic field is expected to be at very quiet levels on June 30 - July 2.
