// CESSI SPACE WEATHER BULLETIN // 16 JUNE 2025 // NOMINAL SPACE WEATHER CONDITIONS // A recent M8.4-class solar flare was observed from Active Region (AR) 14114, which has been flagged as flare-productive by the CESSI flare forecasting model. This region is exhibiting signs of increasing magnetic complexity, and further M- or X-class flares are anticipated. In addition, AR 14110 and AR 14105 are also identified as flare-productive, indicating a sustained risk of flare-induced ionospheric disturbances in the coming days. A Coronal Mass Ejection (CME) associated with the M8.4 flare was detected; however, current analysis suggests it is unlikely to be Earth-directed, and thus the chances of geomagnetic impact remain low. Several small to medium-sized filament structures are visible on the Earth-facing side of the Sun, which could launch Earth-directed CMEs if they erupt. The solar wind speed is currently around 400 km/s. A large coronal hole located in the southern hemisphere of the visible solar disk is expected to contribute to a slight increase in solar wind speed in the coming days due to high-speed solar wind streams.
