Abstract

Nova V1974 Cygni was discovered by Collins (1992) on Feb 19 1992 (t 0) still in its brightening stage (final rise) as a nova of magnitude V = 6.8. The nova reached the principal maximum V0 ~4.4 on Feb. 22.5. It is then one of the brightest novae in 20 years. The appearance at the end of April of forbidden lines of [Ne III] and [Ne V] and their strengthening is sufficient to qualify V1974 Cygni as a “neon nova”.
