MASTER OT J023036.19+291256.9 - PSN

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 02h 30m 36.19s +29d 12m 56.9s on 2013-01-15.67664 UT. The OT unfiltered magnitude is 18.2m (limit 19.7m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2012-12-07.77747 UT with unfiltered magnitude limit 20.3m. There are 3 SDSS galaxy around OT: J023036.11+291256.9 (rmag=22), J023035.45+291254.6 (rmag=19.8) and J023036.16+291308.0 (rmag=19.3). Galaxies offsets are 1 arcsec , 10 arcsec and 11 arcsec correspondingly.

Spectral observations are required.
