Scientific paper

Observations using EMI 6256B photomultipliers of the eclipsing binary system VV Cephei (period 20 years), whose components are M-type supergiant and Be stars, were undertaken at three different sites in Japan. The reflector diameters measured 25, 30, and 91 cm. The error for a single observation, even under unfavorable conditions, is reported at less than 0/m/.02 for all three observatories. Attention is given to the light variations which were found to occur on the eclipsing component.
