Abstract
Photoelectric UBV observations of the central star of the planetary ne bula NGC 2346 obtained during 60 nights between October 1991 and Febru ary 1992 are presented (Tables 1 and 2). Four minima have been stated and can be interpreted in terms of occulting dust clouds, probably rep resenting dense condensations of the planetary nebula. We derived R = A(V)/E(B-V) = 4.0.
