Gromadzki (Warsaw), Subo Dong, Subhash Bose (KIAA-PKU)ASAS-SNCVASAS-SNThe spectrum shows a very blue continuum with H I Balmer absorption lines, with H-alpha filled in but not obvious emission reversal. The EW of H-beta is 6.6 Angstrom, and its FWHM is 41.3 Angstrom. We interpret the spectrum to be that of a typical Dwarf Nova in outburst.2018TNSCR1253....1B
