Cikota (CAHA) None M dwarf 0 1 We obtained the spectrum with the GMOS instrument at the Gemini South telescope as part of our bad-weather filler program. This program is designed to make productive use of poor observing conditions by obtaining spectroscopic observations of recently discovered transients, with the aim of providing timely classifications to the community. The observation was obtained with the grism R150 with a slit of 1.5", combining two 600-second exposures, with a 20 nm shift between the two central wavelength settings in order to compensate for the gaps between the detector chips. The data was reduced using the standard Gemini data reduction software DRAGONS, following the procedures provided by the observatory. The classification was inferred by spectral matching. 2026TNSCR1578....1C
