Title: Recent Novae: Where Are They Now?

Abstract: The Stony Brook/SMARTS nova program now includes spectroscopic and photometric data on 87 novae which have erupted since 2004. We lost the ability to observe [Ne V], an important clue to the cosmologically- important neon abundance, and the ability to obtain low resolution spectra of faint novae approaching quiescence, with the retirement of the RC spectrograph in 2012. We revisited some of these fading novae using the Blanco/COSMOS in May 2015. We propose here to obtain low resolution spectra of fading novae using the SOAR/Goodman spectrograph. The goals are to A.) measure the [Ne V] $lambdalambda46/3426 emission, which can be used to estimate the neon overabundance, which is indicative of a massive O-Ne-Mg white dwarf, and B.) obtain high S/N red spectra to detect the cool donor star. Our targets will be 2 years closer to quiescence than they were in 2015.
