Mingxin Wu (USTC), Ning Jiang (USTC), Linna Xu (USTC), Shifeng Huang (USTC), Yibo Wang (USTC), Tinggui Wang (USTC), Chengyi Wang (USTC), Jiazheng Zhu (USTC) report/s a classification of object: AT 2025afsj
Type: TDERedshift: 0.1654
Remarks: The spectrum shows a significantly bluer continuum compared to the archival SDSS spectrum of the host galaxy and exhibits a prominent broad He II λ4686 emission line, along with a substantial increase in the flux of broad Balmer lines. These spectral characteristics are consistent with those of tidal disruption events (TDE-H+He). So we tentatively classified AT2025afsj as a TDE in AGN.
The following Classification spectrum was provided:
Obsdate: 2025-12-20 00:00:00
Instrument: YFOSC
