Moderately strong M1.4 solar flare erupts from AR 2974

A moderately strong solar flare measuring M1.4 at its peak erupted from Active Region 2974 at 05:26 UTC on March 25, 2022. The event started at 05:02 and ended at 05:50 UTC.

The eruption was associated with a Type II Radio emission at 05:14 UTC, with an estimated velocity of 959 km/s. Type II emissions occur in association with eruptions on the Sun and typically indicate a coronal mass ejection is associated with a flare event.

Additionally, a Type IV Radio Emission was registered at 05:22 UTC. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong coronal mass ejections and solar radiation storms.

The eruption caused a short-lived R1 Radio Blackout from eastern Africa and the Middle East to Japan and Australia.

Analysis of this event is still in progress. There is a possibility of a glancing blow around March 28.
