Abstract:
The eclipsing binary MM Cas (alpha_1980 = 0h53.4m and delta_1980 = +54d20.5') was
observed photoelectrically during 13 nights from December 1980 to September
1982 with the 104 cm telescope of the Uttar Pradesh State Observatory to obtain
the full UBV light curves. The telescope was equipped with a refrigerated
EMI 6094S photomultiplier and standard UBV filters. The light curve obtained
in V filter is given in Figure 1, the phases have been computed according to
the ephemeris:
