Abstract:
A total of 2097 photometric observations in the BVIC system are
presented for 117 Cepheids located in the southern hemisphere. The main
purpose of the photometry is to provide new epochs of maximum
brightness for studying Cepheid period changes, as well as to
establish current light elements for the Cepheids.
