New eJAAVSO: Light Curve of the Eccentric Eclipsing Binary GSC 3152-1202, by R. K. Buchheim

Abstract

A complete light curve of this eccentric (~2.094d) eclipsing binary system has been determined, in B, V, and R bands. The primary and secondary minima are slightly different in depth, and the color index does not change during either primary or secondary eclipse. Newly-determined times of minimum confirm the previously-suspected rapid change in the orbital phase of the secondary minimum, implying significant apsidal motion.
