TNS Classification Report No. 4239 [ 2019TNSCR.964....1P ]
Date Received (UTC): 2019-06-09 10:45:33 Sender: Andrea Pastorello
Group: Padova-Asiago
Andrea Pastorello report/s a classification of object: AT 2019gvn
Type: CV
Remarks: 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.
The following Classification spectrum was provided:
Obsdate: 2019-06-09 01:55:12
Instrument: BC-Ekar
Telescope: Asiago Ekar Telescope
Remarks: The observation was performed on 2019-06-09.08 UT with the Asiago 1.22 m Galileo Galilei Telescope equipped with the B&C spectrograph (grt 300, range 330-790 nm; resolution 0.6 nm).
