OT MASTER161812.44+362852.8 - bright PSN in PGC2081417

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 16h 18m 12.44s +36d 28m 52.8s on 2012-03-24.85193 UT. The OT unfiltered magnitude is 15.5m (limit 18.8m).

The OT is seen in 3 images. There is no minor planet at this place. There is PGC2081417 galaxy with 0.2W 10S offset.

We have reference image without OT on 2011-06-28.67743 UT with unfiltered magnitude limit 20.0m.

Spectral observations are required.
