Description
The Calorimetric Electron Telescope (CALET), launched to the International Space Station in 2015, provides more than 9 years of continuous observation of the radiation environment at low Earth orbit. Using this dataset, we present 5 months of observations following the May 2024 solar storms and the effects they had on the radiation belts across three electron energy ranges (>1.5, >3.4, and >8.1MeV). We show that this event populated a long-lasting new structure of relativistic electrons extending to values of L shell below the slot region barrier of L = 2.8. Additionally, we observe the decay rates for this population as a function of energy and L shell to show the evolution of this structure over time.
