Craig Pellegrino (UCSB/LCO), D. Andrew Howell, Jamison Burke, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran report/s a classification of object: SN 2022ffg
Type: SN IIRedshift: 0.012
Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe II at early phases. The supernova is closest to CGCG 093-074 (z = 0.011994, 2016SDSSD.C...0000:; value from NED). This redshift is well-matched by narrow flash features in the spectrum, including emission lines of H, He I, He II, and CIII. The ATLAS cyan-band apparent magnitude roughly coeval with the spectrum is approximately 17.1, which is roughly 1.5 magnitudes brighter than the non-detection one day prior. The rapid rise and flash features indicate that the SN is young. Further followup is encouraged.
