We present the most complete emission spectrum for inflated hot JupiterHAT-P-41b combining new HST WFC/G141 spectrum from the Hubble PanchromaticComparative Exoplanet Treasury (PanCET) program with archival Spitzer eclipseobservations. We found a near blackbody-like emission spectrum which is bestfitted with an isothermal temperature-pressure (TP) profile that agrees wellwith the dayside heat redistribution scenario assuming zero Bond albedo. Thenon-inverted TP profile is consistent with the non-detection of NUV/opticalabsorbers in the transit spectra. We do not find any evidence for significantH$^-$ opacity nor a metal-rich atmosphere. HAT-P-41b is an ideal target thatsits in the transitioning parameter space between hot and ultra-hot Jupiters,and future JWST observations will help us to better constrain the thermalstructure and chemical composition.
