Abstract
The Electrohotometric observations of a variable star 21 Com in UBV system were performed with the Abastumani astrophysical observatory reflector AZT-14 in 1972-1974. The measurements were fulfilled relative to 22 com. Table 1 gives the differences in magnitudes. The average values of m for each night are listed in Table 2. The observations obtained turned out to be presented only by the period value of 1.10. The light curves in B and V colors and that of color index are given in FIg.2. Rapid light variations with a considerable amplitude have been observed during some nights.
