Solar alert

Issued on 2024 Dec 29 1233 UTC

At 07:18 UTC on December 29, 2024, an X1.1-class solar flare was observed. Such events are typically associated with moderate radio blackouts on the daytime side of Earth. This flare originated from SIDC Sunspot Group 349 (NOAA Active Region 3936), located at N10W33. The region exhibits a Beta-Gamma-Delta magnetic configuration, indicating significant complexity and a high potential for continued activity. At present, no associated solar energetic particle events or coronal mass ejections have been detected.

At 06:12 UTC on December 29, 2024, a halo Coronal Mass Ejection (CME) was detected in SOHO/LASCO-C2 imagery. The CME was observed in the southeast direction with a projected average speed of 767 km/s in the plane of the sky, ranging from 568 km/s to 918 km/s. No significant flares or dimming events have been observed on the visible solar disk that could be conclusively associated with this CME. Current analysis suggests the CME originated from the far side of the Sun and is not expected to impact Earth.
