An M5.5 class flare occurred on the Sun

(ORDO NEWS) — On January 20, 2022 at 06:01 UTC, a strong M5.5 solar flare erupted from active region 2929 at its peak. The event started at 05:41 and ended at 06:12 UTC.

Type II radio emission with an estimated velocity of 329 km/s was recorded at 05:57 UTC.

Type II ejections occur in association with solar eruptions and usually indicate a coronal mass ejection associated with a flare.

Type IV radio emission was detected at 06:17 UTC. Type IV ejections occur during large eruptions on the Sun and are usually associated with strong coronal mass ejections and solar radiation storms.

In addition, this event was associated with a 10 cm radio burst lasting 26 minutes with a peak flux of 350 sfu.

The 10 cm radio burst indicates that the electromagnetic burst associated with the 10 cm solar flare was twice or larger than the initial 10 cm radio background. This may indicate significant radio noise due to the solar flare. This noise is usually short-lived but can interfere with sensitive receivers including radar, GPS and satellite communications.

Region 2929 has a Beta magnetic configuration and is capable of producing strong solar flares, but its location on the western limb does not favor Earth-bound coronal mass ejections.

A storm of proton solar radiation occurs, reaching S1 – Minor levels. This happens about 50 times per solar cycle.

The CME associated with the M1.5 outburst at 17:44 UTC on January 18 has been analyzed and determined to be a possible Earth glancing impact.

The passage of the CME is likely to occur on January 22, judging by the speed and trajectory of the ejection.
