Space Weather Bulletin

25 April 2025
Solar activity is very low with the background X-ray flux at lower C-class levels. There are twelve sunspot regions on the visible solar disk with simple to slightly complex magnetic configurations. The solar wind speed is at elevated to strong levels with speed ranging between 460-630 km/s due to the high-speed stream (HSS) from coronal hole 34 (CH34/+). There are filaments and prominences on the visible solar disk and will continue to be monitored for any potential lift-offs. No Earth-directed CMEs were observed. Geomagnetic conditions are at quiet to active levels (Kp 1-4). Local HF working frequencies are near monthly predicted values.
