Pastorello (INAF Osservatorio Astronomico di Padova)Padova-AsiagoCV0Padova-AsiagoThe spectrum shows a blue continuum with higher Balmer lines in pure absorption, while Halpha is filled by its emission component and Hbeta shows a weak emission core surrounding broad absorption troughs. These features are typically seen in CVs soon after the outburst. 2020TNSCR2854....1T
