Description

Basing on the photographic photometry, generally in R(0.63) and V passbands, new results of light variations for six infrared carbon stars are given. For 4 stars - AFGL 2232, AFGL 2699, AFGL 2881 and BC 56 - cyclic light variations and their periods have been found. For 3 of them - AFGL 2699, AFGL 2881 and BC 56 - secondary variations have been observed. The secondary variations in brightness should be interpreted in terms of the star envelope changes
