Scientific paper

Photometric observations were made during the summer of 1984 of the short-period dwarf Cepheid XX Cyg. The light curves of XX Cyg taken with B and V filters are presented, as well as current estimates of various parameters inferred from them. Among these parameters are an accurate determination of the period and the change in visual light output. In addition, the light curves suggest a small migrating bump that slowly changes in shape and position over many periods, and may even disappear altogether.
