Turatto (INAF Osservatorio Astronomico di Padova) Padova-Asiago CV 1 Padova-Asiago The spectrum shows a blue continuum with narrow Halpha, Hbeta and Hgamma in emission at the rest wavelength. The transient is therefore a cataclysmic variable (CV). The Balmer decrement from the emission components, with the presence of a fairly strong Halpha and higher members of the series showing progressively stronger absorptions, confirms the classification as a dwarf nova. Also the He I emission at 587.6 nm is clearly visible 2019TNSCR2214....1T
