Moses Mlangeni (UCT/SAAO), Lutho Booi (UCT/SAAO), Francois Campher (UCT/SAAO), Gavin Ramsay (Armagh), Victor Moloi (UCT/SAAO), Paul Groot (Radboud/UCT/SAAO) report/s a classification of object: AT 2026fhe
Type: CVRedshift: 0.001256
Remarks: We obtained an optical spectrum of AT2026fhe on 2026-03-11T22:26:23 UTC using the Lesedi 1.0-m telescope at the South African Astronomical Observatory (SAAO) equipped with the Mookodi spectrograph. The target was observed at coordinates RA = 13:59:20.756, Dec = −37:50:06.75 (J2000). The data were reduced using the Mookodi spectroscopic pipeline, and the resulting spectrum was analysed with SNID-Sage, which yielded a best-fit redshift of z = 0.001256. The spectrum is characterised by a blue continuum with a prominent emission feature consistent with Hα (6563 Å). The shorter-wavelength region of the spectrum is relatively noisy, and while weak structure is present, additional Balmer lines such as Hβ and Hγ are not unambiguously detected in the current spectrum. The combination of a blue continuum together with strong Hα emission is commonly observed in accreting cataclysmic variable systems, particularly dwarf novae during or near outburst phases. No spectral features consistent with supernovae are present. We therefore classify AT2026fhe as a cataclysmic variable (CV), likely a dwarf nova, based on its spectroscopic properties. Archival observations from the ATLAS experiment show repeated outbursts over the past years and the object has been identified as
