Pavel Balanutsa report (Atel 4570): MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 38m 55.64s +16d 49m 43.5s on 2012-11-12.96933 UT. The OT unfiltered magnitude is 18.0m (limit 19.7m). The OT is seen in 7 images. There is no minor planet at this place. We have reference image without OT on 2010-12-03.84887 UT with unfiltered magnitude limit 22.5m. The PSN has 1.3E and 21.8N arcsec offset from PGC1517827 galaxy There is SDSS8 galaxy J033855.75+164940.6 with 3.2 arcsec offset (Rmag = 22.5). Spectral observations are required.
