Andrew Howell (UCSB/LCO), Curtis McCully (UCSB/LCO) None SN Ib-pec 0.00472 1 We report the re-classification of SN 2025coe as SN Ib-pec. The recent spectrum shows a best match to Ib-pec SN 2005bf from SNID (Blondin & Tonry 2007, ApJ, 666, 1024). The spectral evolution matches Ca-rich Ib transients like SN2021gno and SN2021inl. The supernova could be a possible Ca-rich transient, but strong Ca is not yet developed. The redshift is acquired from a significant offset from the suspected host of NGC 3277 (z=0.004720, value from NED). Additional follow-up is encouraged. 2025TNSCR.914....1A
