The light curve of QZ Aurigae, plotted with data from Gessner.[4]

QZ Aurigae, also known as Nova Aurigae 1964, was a

objective prism photographic plate taken at the Warner and Swasey Observatory on 4 November 1964.[5] Examination of pre-discovery plates from Sonneberg Observatory showed that the eruption occurred in early February 1964, and it had a photographic magnitude of 6.0 on 14 February 1964. Its brightness declined in images taken after the 14th, suggesting that its peak brightness was above 6.0.[6]
It was probably visible to the naked eye for a short time.

QZ Aurigae is classified as a "fast nova", because it dropped from peak brightness by three magnitudes in less than 100 days.[7]

All novae are binary stars, with a "donor" star orbiting a

spectral type of K1.[10]
