Bulletin: Current Conditions

08 November 2025

Solar activity was at moderate levels with background X-ray flux at C-class levels. Multiple C-class solar flares and a single M-class solar flare were observed in the past 24 hours. The largest of these solar flares reached M1.8 at its peak at 07:16 UT on 07 November from AR4274. This solar flare was associated with a coronal mass ejection (CME). Initial analysis suggests this CME has an Earth-directed component; however, this is still subject to further analysis. Besides this CME, multiple other CMEs, from filament eruptions, with potential Earth-directed components were observed. There are seven sunspot regions on the visible solar disk showing simple to complex magnetic configurations. The solar wind speed was at strong to very strong levels with speeds ranging between 600-860 km/s due to a combination of high-speed stream (HSS) influences from coronal hole 94 (CH94/-) and CME arrivals. There are multiple filaments and prominences on the visible solar disk that show instability and will be monitored for a
