Issued on 2025 Jan 23 2228 UTC

A partial halo coronal mass ejection (CME) has been first observed in SOHO/LASCO-C2 images at 11:36 UTC on Jan 22. This CME was associated with a M1.3 flare, which peaked at 11:08 UTC on Jan 22, produced by SIDC Sunspot Group 346 (NOAA Active Region 3961, S16 W15) and the filament eruptions near the same AR. Associated type II radio emissions were detected at 10:58 UTC during the flaring activity. Associated southward coronal dimming and the EUV wave were also observed. With its source region closer to the central meridian and with a projected speed of about 600 km/s, it is expected to impact the Earth on Jan 25.
