MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 00h 57m 40.99s +44d 31m 01.5s on 2013-11-06.56169 UT. The OT unfiltered magnitude is 15.4m (limit 19.6m). The OT is seen in 3 images. There is no minor planet at this place. The OT have 9590.3E 11693.5N arcsec offset from Andromeda center. We have reference image without OT on 2012-09-24.78772 UT with unfiltered magnitude limit 20.9m.

There is SDSS and Galex source at this place with M~21. So, OT is probably Milky Way CV.

Spectral observations are required.
