We propose a 60ks observation of a new bright (V<7.5) nova likely tobe detected in gamma-rays. The observation will probe shocks withinthe nova ejecta constrain the non-thermal particle acceleration and gamma-rayproduction mechanisms. We will put an upper limit on the particle accelerationefficiency by comparing thermal X-ray and optical to GeV luminosity and searchfor predicted non-thermal X-rays. Understanding shocks in novae is r^ant forother shock-powered transients including Type IIn supernovae tidal disruptionevents and stellar mergers. NuSTAR is the only instrument capable of detectinghard X-rays from novae simultaneously with the GeV emission. [truncated! Please see actual data for full text]
