We performed the spectroscopic observations of SN 2018imd using 1.5-m Kanata telescope on Nov 29.9. The spectrum is similar to those of SNe Ia around the 2 month after the maximum date. GELATO suggests that the spectrum is close to 1991bg at 61 days after the B-band maximum date (Harutyunyan et al., 2008, A&A, 488, 383.).
