Abstract
Electrophotometry of a magnetic variable 21 COM The electrophotometric observations of a variable star 21 Com in UBV system were performed with the Abstumany Astrophysical Observatory reflector AZT-14 (d=48cm) in 1972-1974. The measurements were fulfilled relative to 22 Com. Table 1 gives the differences in magnitudes: ∆ m=21 Com - 22 Com. The average values of m for each night are listed in the 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 ∆ (B-V) are given in fig.2. Rapid light variations with a considerable amplitude (Fig. 4 and 5) have been observed during some nights.
