Discovered Stanislav Korotkiy and Vladimir Gerke using 0.40-m f/8 reflector + unfiltered CCD (STL-11000M) under the limiting magnitude = 20.0R at Ka-Dar Observatory, TAU Station, Nizhny Arkhyz, Russia (MPC COD C32). Mag=17.8CR +-0.2 mag, astrometry: RA=00 41 23.02; DEC=+40 46 56.0 (+-0.2″) URL: http://www.astroalert.su/files/pnv_j004123024046560_2011-09-08_120sec.jpg Three images caught this object. Image taken on Aug. 27.8 UT does not detect the object (limiting mag 20.0R). No object in: MPChecker, VSX AAVSO and SIMBAD. Near to these coordinates seen star in SDSS-III (mag near 20.5R) LGGS J004122.84+404655.6 (mag = 21.8R) Offset is approximate.

Vitaliy Nevski at Vitebsk observatory (near Vitebsk, Belarus, MPCCOD: B42). Images, obtained on Sep 10.875 with 0.3-m reflector + CCD, yield position end figures 23s.00, 56".3 (UCAC-3 catalogue) and the following magnitude 16.5U. Nothing is visible at this position on a Palomar Sky Survey DSS image obtained on 1989-10-01 (via the Digitized Sky Survey; limiting red mag 21).
