We report on spectroscopic follow up of the optical transient PNV J06095740+1212255 which was discovered by Shigehisa Fujikawa, Kan'onji, Kagawa, Japan on 2018-08-07.7984UT ( http://www.cbat.eps.harvard.edu/unconf/followups/J06095740+1212255.html>CBAT )
On 2019-08-14.44UT, we obtained a 120 s low (R ~ 900) resolution spectrum using the Goodman spectrograph (Clemens et al. 2004, SPIE, 5492, 331) on the 4.1 m SOAR telescope. The spectrum shows broad emission lines of H I, He I, N II, and O I. We measure a FWHM of around 4000 km/s for Halpha and 3500 km/s for Hbeta, indicating very high expansion velocities. The overall spectrum is that of a very fast expanding classical nova outburst of the He/N spectroscopic type (Williams 2012, AJ, 144, 98) and possibly in the post-maximum stage.
We encourage follow up observations in all bands.
Emission line identifications:
H I: 3889, 3970, 4102, 4340, 4861, and 6563A
He I: 4471, 5016, 5876, 6678, and 7065 A
N II: 5001, 5679, and 6364 A
NIII: 4638? A
O I: 7773 A
We thank the SOAR director Jay Elias for enabling these observations.
