Masayuki Yamanaka report/s a classification of object: SN 2018imf

Type: SN IIP
Redshift: 0.0036

Remarks: We performed the spectroscopic observations of AT 2018imf, whose spectrum exhibits the P-Cyg profile of H-alpha and its absorption minima reaches 6000km/s. The spectra also exhibits absorption lines of NaI D and Ca II IR triplet. These features are consistent with those of Type IIP supernovae. GELATO (Harutyunyan et al., 2008, A&A, 488, 383) suggests that this SN resembles with Type IIP SN 2009bw at 60 days.
