- Аннотация: Five-color light curves of AC Cnc with a phase coverage of a large part of the orbital cycle and with a 12-45-s time resolution have been obtained. The light of AC Cnc at orbital phase 0.0 does not change significantly. The depth of the primary minimum, the color indices U-B, B-V, V-R, and V-I, and noneclipse light in UBVRI undergo periodic '11-day' oscillations. The duration of the total eclipse in the primary minimum is about 4-8 min in the active stage and about 8-15 min in the quiescent one. There is a noticeable increase of light in the RI, and it is suggested that it is due to the effect of the reflection on the secondary.
