Scientific paper

The short-period eclipsing binary system TY Boo was observed on five consecutive nights. The observations covering the eclipse portions of the light curves yielded five epochs of minimum light. A period study gives no indication of the cyclic period variation indicated by Szafraniec. The light curves, defined by 348 observations with the B filter and 353 with the V filter, are of the W Ursae Majoris type and are symmetric. The system becomes redder during each eclipse with a momentary dereddening at phase 0.0. The depths of the eclipse curves are about the same as those in the light curves published by Carr. However, the system appears to have undergone a slight reddening.
