MASTER033305.88+171901.5 - PSN?

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 03h 33m 05.88s +17d 19m 01.5s on 2012-03-06.56171 UT. The OT unfiltered magnitude is 17.0m (limit 17.3m). The OT is seen in 1 image. There is no minor planet at this place.

We have reference image without OT on 2011-10-25.75287 UT with unfiltered magnitude limit 19.44m.

Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/033305.88171901.5.png
