We have obtained one spectrum of Gaia21bcv with SPEX during the occultation episode on 2021 Apr. 18 (MJD 59322) with a total of 7000s on-object exposure time that is of low-SN and shows no identifiable features. A K5 spectral type, determined from the optical spectra, would have strong CO bandhead absorption at 2.3 ����¯�¿�½������¼m. We propose now to obtain a better near-infrared spectrum during the quiescent (unobscured) condition of the star. This will serve to ascertain the spectral type and study potential veiling of the photospheric absorption spectrum that would explain why CO bandhead aborption was not observed in the first spectrum.
