Our observations of an area in Auriga were performed in the observatory of the Siberian State Aerospace University with a Hamilton telescope (D = 400 mm, F = 915 mm) equipped with an FLI ML9000 CCD chip (3056x3056 pixels, pixel size 12 μm). We obtained all unfiltered CCD observations during two time intervals: January 2011 – March 2011 and October 2011. Exposure times were 30 seconds for all frames. The size of the field is 2°.3 × 2°.3. The magnitudes were referred to red magnitudes of comparison stars from the USNO-A2.0 catalog (Monet et al. 1998). We used VaST (Sokolovsky & Lebedev 2005) software to search for new variable stars. To find periods, we applied WinEfk software provided by Dr. V.P. Goranskij. Observations for several stars can also be found in the ROTSE-I/NSVS survey (Wozniak et al. 2004).
