(a): Spectral energy distribution (SED) of AT 2024pvu from UV to MIR. Blue points represent the host galaxy SED in the quiescent state. The black line indicates the best-fitting model from CIGALE with the minimum χ². We show GALEX and Swift UV photometries as red pentagrams and red triangles, respectively. The SWIFT measurement agrees with the CIGALE prediction (open black circle with error bar), whereas the GALEX measurement shows a significant excess. (b): Spectral energy distribution (SED) of the CRTS flare at the time of the GALEX observation, with blackbody models fitted using MCMC.
