Abstract (from CDS):

S. Korotkiy, Moscow; and T. Kryachko and B. Satovskiy, Kazan State University (KSU), report mag approximately 12.4 from an unfiltered 300-s CCD image taken on Sept. 1.834 UT with a 8.0-cm f/7.5 ED refractor (+ SBIG ST-2000XM camera) at KSU's Astrotel Observatory (Karachay-Cherkessia, Russia). They provide position end figures 25s.43, 18".7 (each ± 0".1); comparison with a Palomar Oschin Schmidt telescope plate (via Digitized Sky Survey) obtained on 1992 Dec. 22 shows an apparent star at this position with blue mag about 20.5. Their image is posted at the following website URL: http://www.astroalert.su/files/novaand2008.jpg. Photometry of the variable obtained by T. Kryachko, S. Korotkiy, D. Denisenko, and B. Satovskiy with the same 8.0-cm refractor during Sept. 1.843-1.934 clearly shows a humped light curve with an amplitude of 0.13 mag and a period of 0.055(1) day, which is typical for U Gem/WZ Sge-type cataclysmic variables. Korotkiy also forwards the following additional CCD magnitudes (unfiltered unless otherwise noted) and position end figures for the new variable from other observers in Belarus and Russia: Sept. 1.821, 12.5, 25s.43, 19".0 (S. Shurpakov, Baran, Belarus, 19.0-cm f/5 reflector + Artemis 285 CCD camera); 1.836, B = 12.9, V = 13.0, R = 13.3, 25s.42, 18".4 (M. Andreev, Terskol, Kabardino-Balkaria, Russia, 28.0-cm f/6.8 Celestron 11 NexStar GPS + Apogee 47E Alta CCD camera); 1.842, 12.2, 25s.63 ± 0".34, 17".45 ± 0".27 (I. Chekalin, Taganrog, Russia, 18.0-cm f/4 reflector + Canon 350Da DSLR camera); 1.846, 12.3, 25s.39, 18".7 (V. Nevskiy, Vitebsk, Belarus, 30.0-cm f/5 reflector + QHY-6 CCD camera).
