Mikuz, Crni Vrh Observatory, reports that a new star-like variable object (R = 16.2 +/- 0.1) was discovered by B. Mikuz on four filtered CCD images (limiting mag 18.5) taken during Aug. 22.905-22.933 UT in the course of the PIKA project at the Crni Vrh Observatory, using the 0.60-m f/3.3 Cichocki telescope. The new object is located at R.A. = 21h05m12s.29, Decl. = +69d12'55".3 (equinox 2000.0). Nothing is visible at this position on PIKA archival images taken on 2004 Nov. 27 (limiting mag 17.0) and 2006 Sept. 3 (limiting mag 18.7) or on several Palomar Sky Survey and 2MASS images from the Aladin database. Further investigation of the Simbad and VizieR databases shows no candidate object at this position. Additional photometry by B. Mikuz: Aug. 26.865, R = 16.5 +/- 0.1; Aug. 29.837, R = 16.8 +/- 0.1.
