42392019-06-09 10:45:33pastoAndrea PastorelloPadova-AsiagoCVPadova-Asiago The low signal-to-noise spectrum of AT2019gvn (a.k.a. BraTS-SON-T2-006; discovered by the Brazilian Transient Search (BraTS) team; TNS Astronomical Transient Report No. 36916), shows a blue continuum with absorption lines of the Balmer series at redshift 0. This suggests the transient being a Galactic stellar source, most likely a cataclismic variable. 2019TNSCR.964....1P
