Abstract:
Here we report on the classifications of 7 Type Ia supernovae and one transient that only shows blue continuum.

These were found primarily by searches of bright (<19 mag in r- or g- band) ZTF targets, and where possible, supplemented with Superphot+ (de Soto et. al, 2024, ApJ, 974, 169) candidates with >50% core-collapse probabilities. We list the transients by name, newly found classifications, and time of spectroscopic observation below. All classifications are performed using the Next Generation Supernova (Goldwasser et al 2022, astronote/2022-191). The we only find a blue continuum in the spectrum of AT2025cfq.
