Abstract:
We report the classifications of 4 Type Ia's and 1 Type II.

Here we report on the classifications of 5 transients, triggered on Superphot+ (de Soto et. al, 2024, ApJ, 974, 169) candidates with >50% core-collapse probabilities and a latest ZTF observation brighter than 18.5 magnitudes in either the r- or g-band. We list the transients by name, newly found classifications, and time of spectroscopic observation below. All classifications are performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and confirmed using Astrodash (Muthukrishna, Parkinson, and Tucker. ApJ 885.1: 85.).
