A major solar flare measuring X1.2 at its peak erupted from Active Region 3182 at 00:57 UTC on January 6, 2023. The event started at 00:43 UTC and ended at 01:07 UTC.
A 10 cm Radio Burst (Ten flare), with a peak flux of 420 sfu and lasting 3 minutes, was associated with this event.
A 10 cm 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.
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.
The location of this region — close to the east limb — does not favor Earth-directed coronal mass ejections (CMS). However, this will change in the days ahead as it rotates toward the center of the solar disk.
This region is most likely the source of a large asymmetric partial halo CME detected on January 3:
Analysis of this event is still in progress.
