- Аннотация: Results of UBVRJHKLMN photometry of R CrB from May 26, 1977 to January 8, 1978 are presented. Color variations in the optical bands during the minimum period are found to have a complex character. A general tendency is indicated that the brighter the star the redder it is. IR flux in the I and H bands was found to be smaller in relation to the K band in the minimum period, thus indicating that the energy distribution is shifted from the near-IR to longer wavelengths. It is also shown that the energy distribution at 1-10 microns can be represented by a combination of two sources: an external optically thin dust shell with a temperature of 700 K and dust clouds (1850 K) which absorb light from the star.
