*********************************************************************** Product: Daily Forecast of Geomagnetic Activity Issued: 2026 January 06 06:23UTC Prepared by the Athens Space Weather Forecasting Center ***********************************************************************
I. Solar activity --Current Status Solar Flux (10.7cm) measured on 05.01.2026 at 23:00 UTC was 154 sfu. The background X-Ray flux is at the class C1.3 level. No obviously Earth directed CMEs were observed in available LASCO imagery on January 02-04. An equatorial coronal hole (CH1338) will like become Earth facing on January 06-08.
II. Solar Energetic Particle Events Protons and electrons fluxes are quiet.
III. Interplanetary and Geomagnetic conditions The solar wind speed measured by ACE satellite reached the max value 439 Km/s on January 05 at 06:55 UT during the last 24 hours. The solar wind speed from STEREO A was detected 400 Km/s during the last 24 hours. The vertical component of IMF Bz reached the max value -7 nT on January 05 at 11:30 UT during the last 24 hours. The geomagnetic field was at quiet to active levels during the last 24 hours. The Kp index now is at quiet levels with Kp=1.
IV. 3-day Geomagnetic Activity Forecast The geomagnetic field is expected to be at quiet levels on January 06-08.
