Abstract:
We report the classifications of 3 transients, including 1 Type II and 2 Type Ia. We also upload the followup spectra of 10 transients.

Here we report on the classifications of 3 transients obtained through the FLWO-1.5m / FAST during 2025-11-21 to 2025-11-24, including 2025abmj, 2025acrr, and 2025acrz. All classifications were performed using SNID-SAGE(F. Stoppa 2025). We also upload follow-up spectra of 10 transients, including 2025aarn, 2025aaxz, 2025abdd, 2025abob, 2025acnj, 2025acsj, 2025aedq, 2025cku, 2025uam, and 2025ztn.
