We report a spectroscopic observation of the supernova candidate AT2024adia with the Keck Cosmic Web Imager (KCWI) Integral Field Spectrograph. The observation was made on 2024 Dec 05 UT. We observed a blue, mostly featureless spectrum with a narrow He II (4686 Angstrom) line with FWHM = 450 km/s. The estimated redshift is z = 0.052 +/- 0.001
based on the location of the H Balmer and O [III] lines.
The object was first reported by ZTF (2024TNSTR4761....1S).

Notes:
(1) When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
