A class M7.4 solar X-ray flare occurred on 2025/01/17 with peak time 13:35UT

Solar flaring activity was high over the past 24 hours, with 7 M-class flares identified. The largest flare was a M7.4 flare (SIDC Flare 3308) peaking on January 17 at 13:35 UTC, which was produced by SIDC Sunspot Group 378 (NOAA Active Region 3964). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 378 (NOAA Active Region 3964) (Beta-Gamma) was responsible for the majority of the flaring activity over the past 24 hours. No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days. The greater than 2 MeV electron flux measured by GOES 16 remained below the 1000 pfu alert threshold, and it is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.

Geomagnetic conditions were globally and locally quiet to active (Kp 4 and K Bel 4). Active conditions are expected in the next 24 hours. Slightly enhanced solar wind conditions are recorded over the past 24 hours, with solar wind speed from 530 to around 610 km/s. The interplanetary magnetic field was initially 10nT and gradually decreased to 4 nT in the last 24 hours and the Bz reached a minimum value of -4 nT. Further enhancements of the solar wind speed are possible in the next 24h, due to the influence of the high-speed stream (HSS) of the coronal hole.
