15164 2023-07-06 16:31:47 Aaron Do Aaron Do (IfA, UH Manoa) on behalf of the SCAT team SCAT SN I 0.02443 1 SCAT SNID (Blondin & Tonry, 2007) presents several fits to type Ic-norm, type IIb, and type Ia-pec. ATLAS and ZTF photometry are consistent in showing a slow, linear rise over the past two weeks that may have peaked a few days ago. With a fiducial cosmology the peak absolute magnitude is around -17 in ATLAS o band and ZTF r band, and around -16.25 in ZTF g band. Redshift from the ALFALFA survey (via NED). 2023TNSCR1580....1D
