Abstract (from CDS):

We present the first results of a multi-site photometric campaign carried out in 2004-2006 on the Algol-type eclipsing binary system CT Her, the primary component of which is a δ Scuti-type pulsator. Our observations include (almost complete) binary light curves in the filters B and V which have been analysed following the principles of the Wilson-Devinney method. After removal of the best-matching light curve solution, the residual B and V light curves have been investigated for their pulsational content.
