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.
A shortwave radio blackout caused by the flare affected Indonesia, Australia, New Zealand, and islands in the south Pacific Ocean.
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 the source of a large asymmetric partial halo CME detected on January 3:
