22049 2025-09-18 15:55:34 Megan Newsome Megan Newsome (UT Austin), Sebastian Gomez (UT Austin) FLEET SN Ia 0.105 1 1 FLEET AT2025uox was selected as a possible TDE by our FLEET program with a P(TDE) = 0.64 (Gomez et al., 2023, ApJ, 949, 113). The redshift of z = 0.105 was determined from the transient features. We find a best match to SNe Ia using NGSF (AstroNote 2022-191, Howell et al. 2005). 2025TNSCR3763....1N
