Noah Franz (UA), Wenkai Li (UA/USTC), Jeniveve Pearson (UA), Aysha Aamer (UA), Brian Hsu (UA), Kate D Alexander (UA), David Sand (UA), Collin Christy (UA), on behalf of the AZTEC collaboration report/s a classification of object: TDE 2026hir

Type: TDE
Redshift: 0.088

Remarks: We classify 2026hir based on a Bok B&C spectrum taken on 2026 April 10 (~17 days after the EP trigger). We ran SNID-SAGE and found the top 10 closest matches are TDEs (closest match is TDE 2018fyk) at redshift 0.088, consistent with the redshift reported in AstroNote 2026-87. The classification is primarily based on the broad HeII feature at 4685 angstroms (rest wavelength), consistent with the line reported in AstroNote 2026-93.

The following Classification spectrum was provided:

Obsdate: 2026-04-10 00:00:00
Instrument: BC-Bok
Telescope: Bok Telescope

Remarks: The narrow absorption features at ~5500, ~6750, and ~7600 angstroms (observed wave) are tellurics and sky lines.
