Scientific paper

The first modern (uvby I) photoelectric observations of the eclipsing system AQ Cas are given. The light is continuously variable at all wavelengths, and light curves are asymmetrical around primary eclipse, particulary in the ultraviolet. Analysis of the colors of the light lost in primary and secondary eclipses yield color excess Eby = 0.64. Continuum stellar colors correspond to effective temperatures near 28,000K and 18,000K for the two stars.
