Scientific paper

New photometric U, B, V observations of the central star of the bipolar planetary nebula NGC 2346 were done in September 1985. The observations confirm the progressive dephasing of the light-curve and show a 'looping' evolution of the colors from 1982 to 1985. The model proposed by Aendez et al. (1982) of a clumpy dust cloud passing in front of the stellar system is confirmed. Following the scenario of Schaeffer (1985), it is suggested that: (1) a part of the dusty material was ejected in early 1982 by the sdO star near the apastre in the direction of the A-star's orbit; (2) the obscuring cloud will probably leave the central star system in 1986.
