We report 0.45-2.0 mm continuum observations of Nova Cygni 1992, the brightest classical nova at visual maximum since 1975. Measurements were obtained 66, 104, 224, 234, 357 and 358 d after outburst. At the earliest epoch of our observations, the data are consistent with free-free emission from an optically thick nebula. The measurements obtained one month later show the nebula becoming progressively more transparent, with a turnover to optically thin emission in the millimetre regime. We find that our millimetre/submillimetre data on the early stages of this nova outburst are inconsistent with kinematical models which have been used to fit the radio data on previous novae at later times.
