Bulletin: Current Conditions

04 September 2026

Solar activity was low with background X-ray flux at B- and C-class levels during the past 24 hours. No significant solar flares were observed during this period. There are three sunspot regions on the visible solar disk with simple magnetic configurations. Solar wind speed was at background levels with speeds ranging between 360-400 km/s. There are several filaments and prominences on the visible solar disk that show minimal movement but will be monitored for any potential lift-offs. No Earth-directed coronal mass ejections (CMEs) were observed in the available coronagraph imagery during the past 24 hours. Geomagnetic conditions were at quiet levels (Kp 1-2). Local HF working frequencies are near monthly predicted values.
