摘要：

Infrared photometry and spectrophotometry of Nova Cygni 1992 taken within 54 days of its eruption show a strong 12.8 mum [Ne II] forbidden emission line as well as hydrogen recombination lines. Spectra with lambda/DELTAlambda almost-equal-to 2000 resolve the [Ne II] and 12.37 mum Hualpha lines with approximately 2200 km s-1 (FWHM). The [Ne II] line shows multiple velocity components. The amount of [Ne II] required to produce the observed emission feature exceeds the solar abundance of neon by at least a factor of 4.
