Аннотация:Infrared photometry of WY Gem and ZZ CMi has shown that the mean value of the colour index (J-K) for WY Gem corresponds to M4 I. No excess radiation is observed. Variability of WY Gem over the observational period did not exceed 0m.20 in all filters. The angular diameter of WY Gem is ≡0arcsec.0035. The mean colour index for ZZ CMi corresponds to M5 III. In the M band (4.7 μm), excess emission possibly exists. The angular diameter of ZZ CMi is ≡0arcsec.0024.
