Abstract
Spectroscopic observations of Nova Cygni 1992 in the range of 0.64–1.15 µm from 1992 February 22 to 24 show a strong increase of emission in the H I, O I, and N I lines, and the onset of the two absorption systems on February 23. there are indications of a strong overabundance of nitrogen.Keywords
