Solar Radiation Storms at S1-S2 (Minor-Moderate) Levels - 23 March 2024
The greater than 10 MeV proton flux became enhanced beginning at around 23/0400 UTC, following an X1.1 flare at 23/0133 UTC from Region 3614 (N17W00, Dso/beta). Flux values exceeded the S1 (Minor) threshold at 23/0815 UTC and the S2 (Moderate) threshold at 23/1405 UTC. Solar radiation storms at S1-S2 levels are expected to continue through the remainder of 23 March and persist into 24 March.
