The optical spectra and photometry of the nova have been taken from SMARTS and Asiago; the NIR photometry was obtained from SMARTS and Mt. Abu. The spectra were dominated by strong H I lines from the Balmer series, FeII, NI, and [OI] lines in the initial days, typical of an Fe II type nova. The measured FWHM for the Hβ and Hα lines was 800-1200km/s. There was pronounced dust formation starting 90 days after the outburst. The J-K color was the largest among recent dust-forming novae. Description: Near-infrared observations were obtained using the 1.2m telescope of Mt.Abu Infrared Observatory from 2012 March 29 to June 18 and the SMARTS/CTIO 1.3m telescope. The SMARTS photometry is available on the SMARTS atlas (Walter+, 2012PASP..124.1057W). Optical spectra were obtained with the Asiago 1.22m telescope + B&C spectrograph. Further low-dispersion spectra and photometry were obtained using the SMARTS 1.5m facilities. We obtained 19 spectra on an irregular cadence and with various sky conditions from 2012 April 5 through 2012 June 24. The target was observed using the COSMOS long slit spectrograph at CTIO on 2015 May 8, some three years after the outburst.
