9006 2021-02-22 14:07:28 Daniel Perley Daniel Perley (LJMU) ZTF SN Icn 0.083 1 ZTF Peak-light spectra show strong narrow/intermediate width P-cygni features of CIII, OIII, and CIV with no evidence of hydrogen or helium, very similar to SN 2019hgp (Gal-Yam et al., in prep) and the recently-reported SN 2021ckj (AstroNote 2021-71). Further discussion of the discovery of this transient is presented in AstroNote 2021-62. We classify this as a member of the newly-proposed "Icn" class. 2021TNSCR.570....1P
