MASTER OT J020906.21+013800.1  - possible OT in PGC Galaxy.

MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 02h
09m 06.21s +01d 38m 00.1s on 2015-12-27.85448 UT.
The OT unfiltered magnitude is 18.3m (limit 20.0m).

The OT is seen in 6 images. There is no minor planet at this place.
There is PGC1200980 galaxy (it seems spiral galaxy and distance about 100
Mpc)  very close to OT. The OT offset are  4.3E   1.5S  arcsec.

We have reference image without OT on 2015-06-07.17962 UT with unfiltered
magnitude limit 18.9m.

Spectral observations are required.

The discovery and reference images are available at:
