MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 21h 43m 51.21s +31d 53m 24.6s on 2011-12-15.49 UT The OT magnitude in 'R' filter is 17.2m (limit 18.4m)

The OT is seen in 2 images. There is no star or minor planet at this place.

We have reference image without OT on 2011-10-28.6 UT with magnitude limit in 'V' filter 18.6 m

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 01h 51m 47.45s +09d 49m 46.3s on 2011-12-21.60 UT The OT unfiltered magnitude is 14.2m (limit 17.5m)

The OT is seen in 6 images. There is no minor planet at this place.

We have reference image without OT on 2011-01-24.53 UT with unfiltered magnitude limit 19.5m

Spectral observations are required.

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 08h 41m 27.37s +21d 00m 54.4s on 2011-12-22.75 UT The OT unfiltered magnitude is 16.9m (limit 19.3 m)

The OT is seen in 2 images. There is no minor planet at this place.

We have reference image without OT on 2011-12-01.83539 UT with unfiltered magnitude limit 19.8m . There is CV CSS 090525:084127+210054 at this place.

Spectral observations are required.
