During observations of the field in Aur, Timur Kryachko, Andrey Samokhvalov and Boris Satovsky (Astrotel Caucasus Observatory, Karachay Cherkessya, Russia) discovered a possible cataclysmic variable at position RA=05:56:40.90 Dec=+34:38:46.8 (J2000). All observations were carried out at Astrotl Caucasus Observatory on 300-mm Ritchey-Chretien telescope, equipped with Apogee Alta U9000 CCD camera without filters. In total of 5 images with 5-minute exposures were obtained on JD 2455885. On the POSSII R plate dated 1989-10-28, POSSII B plate, dated 1997-03-09 and POSSII IR plate, dated 1999-01-23 this object not visible.

This object is identical to the star USNO-A2.0 1200-04082601 (R.A.=05 56 40.89, Decl.=+34 38 47.5, R=18.9, B=19.6) which is visible on the Palomar plates. Color-combined POSS-II BRI image (200"x200" field of view) is uploaded at http://pics.livejournal.com/bigdenru/pic/000b20gy/ Nine images of the field of this variable were obtained by Palomar-NEAT project on three nights in 2001-2002. Magnitudes from the images combined by three (unfiltered with the red zeropoint, using USNO-A2.0 1200-04083580 with R=16.0 as comparison star): 2001 12 19.20, 20.4; 2002 01 04.40, 19.6; 2002 01 15.17, 18.2. Animation of NEAT images from three nights is available at this URL: http://pics.livejournal.com/bigdenru/pic/000b3pgp/ Reported by D. Denisenko.
