Reguitti (UNAB) Padova-Asiago CV 0 1 Add Padova-Asiago The noisy spectrum is similar to that of a Dwarf Nova in outburst, with a blue continuum and broad (FWHM~5,000 km/s) Balmer lines in absorption. The Hdelta line is more prominent than both Hgamma and Hbeta, and Hepsilon is also present, while Halpha is not visible, probably filled by the emission from the accretion disk. 2021TNSCR2563....1O
