R3 (Strong) level flare event on 22 March, 2024 (EDT)

R3 Event on 22 March 2024
R3 (Strong) level flare event on 22 March, 2024 (EDT)
published: Monday, March 25, 2024 17:39 UTC

R3 (Strong) levels were reached on 22 March, 2024. The flare activity began from Region 3614 (to the north), and was still in progress when another flare erupted from Region 3615 (to the south). It's tough to say with certainty at this point which flare was the source of R3 levels, but the flare from 3614 appears to have a likely coronal mass ejection (CME) associated with it. We must await imagery to be sure and began analysis accordingly.
