Moira Andrews (UCSB/LCO), Joseph Farah (UCSB/LCO), D. Andrew Howell (UCSB/LCO), Curtis McCully (UCSB/LCO) report/s a classification of object: SN 2025efc
Type: SN IaRedshift: 0.0163
Remarks: We report the classification of SN 2025efc as SN Ia. The spectrum shows a best match to Ia norm SN 2003W from SNID (Blondin & Tonry 2007, ApJ, 666, 1024) 11 days before peak. The object redshift is acquired from the nearby host of ESO 565- G 019 (z=0.016285, value from NED). Additional follow-up is encouraged.
