Rubin Observatory commissioning alert stream via the Babamul broker (du Laz et al., 2025). The photometry acquired during the first detection epochs (around MJD 61094.19) leads to absolute magnitudes M_g ~ -8.89, M_r ~ -9.03, M_i ~ -9.02. Further, the source shows a fading rate of 0.538 mag/day in r-band, 0.638 mag/day in g-band and 0.424 mag/day in i-band. The lack of reddening disfavours a kilonova or an afterglow scenario. Given the photometric evolution and absolute magnitude, we suggest this is a classical nova candidate. | 2026TNSTR.856....1S | N |
