MASTER J221505.32+101812.6 - PSN

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 22h 15m 05.32s +10d 18m 12.6s on 2012-06-25.95193 UT. The OT unfiltered magnitude is 16.8m (limit 17.5m). The OT is seen in 3 images. There is no minor planet at this place. There are two SDSS8 faint galaxies (rmag>22.5) J221505.40+101814.2 and J221505.40+101814.3 with 2.2 and 2.3 arcsec offsets correspondingly.
We have reference image without OT on 2010-07-16.87120 UT with unfiltered magnitude limit 18.0m.
Spectral observations are required.
