OT MASTER J005552.55+261100.8 discovery

MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 00h 55m 52.55s +26d 11m 00.8s on 2012-08-30.77359 UT by two tube simultaneously during 3 min exposition.
The OT unfiltered magnitude is 14.2m (limit 18.0m).

There is no minor planet at this place. There is no known satellite around 4 degrees at this time.

There is one non star object NBKY021338 (jmag~ 22.3) in the Guide Star Catalog with 3.6 arcsec offset.

There are no Swift, INTEGRAL, Fermi, Konus-Wind alerts at this time.

We have reference image without OT on 2012-08-30.74228 UT (~40 min before) with unfiltered magnitude limit 17.9m.

Follow up observations are required.
