We report on spectroscopic follow up of the optical transient PNV J171200009-4017560 which was discovered by the Brazilian Transient Search - BraTS - at SONEAR Observatory, Oliveira, Brazil on 2020-04-05.29 UT. There was no spectroscopic follow up of this transient around discovery, likely due to shutdown of many observatories.
On 2020-10-23.35 UT, we obtained a low-resolution spectrum using the Goodman spectrograph (Clemens et al. 2004, SPIE, 5492, 331) on the 4.1 m SOAR telescope. The transient is visible in SOAR acquisition images at 17:12:00.18 -40:17:56.6 J2000. The spectrum shows broad emission lines of H I, He I, [O III], and [O II]. The FWHM of Halpha is around 1300 km/s. The overall spectrum is that of a Galactic classical nova well past peak.
This ATel is based on observations obtained at the Southern Astrophysical Research (SOAR) telescope, which is a joint project of the Ministério da Ciência, Tecnologia, Inovações e Comunicações do Brasil (MCTIC/LNA), the U.S. National Science Foundation's National Optical Astronomy Observatory (NOAO), the University of North Carolina at Chapel Hill (UNC), and Michigan State University (MSU).
