The event started at 20:29 and ended at 20:49 UTC. A full-halo coronal mass ejection was produced, with impact expected early to midday on December 9, potentially causing periods of G3 \u2013 Strong geomagnetic storming.<\/p>\n<p>A Type II Radio Emission with an estimated velocity of 1 143 km\/s was associated with the event, suggesting a coronal mass ejection (CME) was produced during the event.<\/p>\n<p>In addition, a 10cm Radio burst lasting 4 minutes and with a peak flux of 1 100 sfu was registered from 20:35 to 20:39 UTC. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background.<\/p>\n<p>This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers, including radar, GPS, and satellite communications.<\/p>\n<p>M8.1 solar flare on December 6, 2025.
