MASTER163105.47+615548.4 - PSN
MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 16h 31m 05.47s +61d 55m 48.4s on 2012-03-14.83877 UT.
The OT unfiltered magnitude is 18.1m (limit 19.8m).
The OT is seen in 5 images. There is no minor planet at this place.
There is one nonstar object in The Guide Star Catalog N4HU009709 with 1.3 arcsec offset (jmag=21.9).
We have reference image without OT on 2011-05-01.72794 UT with unfiltered magnitude limit 20.1m.
Spectral observations are required.
