Eclipsing binaries present in a large variety of combinations. Two such combinations include W UMa stars and Algol-type binaries. The W Uma systems consist of main-sequence stars sharing a common envelope. The Algol-type (detached) variables consist of a main-sequence and a more evolved companion. Both types of systems are interesting because the physical attributes of the system may be obtained from the variability in their light output. CCD observations obtained over 16 days in 2014 for V1191 Cyg and V1187 Cyg are presented. Observations were taken using a 30 cm SCT at 2195 m near Sunspot, NM. The W Uma variable V1191 Cyg was found to have a period of 0.301 ± 0.001 days. The presence of nearby stars made it difficult to obtain an accurate period for the Algol-type binary V1187 Cyg with our current resolution. The ultimate goal of this study is a complete analysis of the light curves for both objects.
