The central star of NGC 2346 is a well known binary with an A-type primary and a hot companion (Méndez and Niemela 1981). The star went through a series of periodic light variations which ceased in 1986 and were interpreted as an eclipse of a dust cloud passing in front of the binary system (e.g. Méndez et al. 1982, Costero et al. 1986). Recently, light variations reappeared with shallower minima compared to the previous eclipse (e.g. Kohoutek et al. 1992).
