The IR to X-ray SED at the peak of the flare at UT 10.5 hr on 2024 April 5. Orange and green points show the JWST and NuSTAR peak luminosities at 4.8 μm, 2.1 μm, and 6 keV. The measurement errors of the JWST measurements are at the 1% level, within the size of the data points. Dashed lines show the power-law extrapolation of the IR spectral index (orange) and the harder power-law spectrum that would connect the 2.1 and 6 keV measurements (gray).
