Major X2.2 solar flare erupts just beyond the southwest limb of the Sun

X2.2 solar flare april 20 2022

A major solar flare measuring X2.2 at its peak erupted at 03:57 UTC on April 20, 2022, from a region located just beyond the southwest limb of the Sun – likely former Region 2992. The event started at 03:41 UTC and ended at 04:04.

The flare was associated with multiple bursts on specific radio frequencies, including a burst of 509 solar flux units on 2 695 MHz.

Additionally, a Type II Radio Emission was detected by the USAF Radio Solar Telescope Network (RSTN), with an estimated velocity of 1 630 km/s. This radio signature is often indicative of a potential coronal mass ejection (CME).

Coronagraph imagery from the NASA/SOHO LASCO instrument are still not available to confirm if a CME took place.

However, as the source region of the flare was beyond the southwest limb, initial analysis suggests any CME is unlikely to have an Earth-directed component.

Other notable events of the day include M1.2 from AR 2994 at 01:14 UTC and M7.2 from AR 2992 at 01:36 UTC.

  1. Just waiting on Jamal to tell us he had this predicted, and that he will show us all as soon as he finds :
    His notes,
    That paragraph in his book that disappears when others look for it,
    His degree and defense,
    That missing webpage, and
    the non-thermonuclear sun that got him tossed from school.
