MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 02h 42m 41.97s +31d 10m 58.0s on 2012-12-07.80490 UT. The OT unfiltered magnitude is 19.2m (limit 20.2m). The OT is seen in 2 images. There is no minor planet at this place. There is SDSS galaxy J024241.93+311058.1 (rmag = 20.3) with 0.5 arcsec offset. We have reference image without OT on 2010-12-03.93150 UT with unfiltered magnitude limit 22.1m. Spectral observations are required.
