MASTER134433.70+224132.3 - Short OT
MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 13h 44m 33.70s +22d 41m 32.3s on 2012-03-11.69947 UT.
The OT is seen in 2 consecutive images. The unfiltered OT magnitude on first image is 18.2. On the second image (3.5 min after first) the unfiltered OT magnitude is 17.8m (both images limit is 18.8m)
There are no minor planet or satellite at this place.
We have reference image without OT on 2011-04-02.78500 UT with unfiltered magnitude limit 21.0m.
There are no GRB events from Swift, Fermi, INTEGRAL, Wind-KONUS at this time.
Followup observations are required.

The OT unfiltered magnitude is 18.1 m (limit 19.8 m).
The OT is seen in 5 images. There is no minor planet at this place.
There is the Guide Star Catalog non star object N4HU009709 ( jmag=21.9) with 1ââ¬Â.3 offset.
We have reference image without OT on 2011-05-01.72794 UT with unfiltered magnitude limit 20.1m.
Spectral observations are required.

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 07h 56m 48.14s +30d 58m 05.4s on 2012-03-13.89994 UT.
The OT unfiltered magnitude is 16.542m (limit 19.6m).
The OT is seen in 2 images. There is no minor planet at this place.
There is Catalina Real-time Transient Survey OT CSS080406 J075648+305805 (Drake et al. 2009, ApJ, 696, 870) near this place.
We have reference image without OT on 2010-12-06.97156 UT with unfiltered magnitude limit 21.0m.
Follow up observations are required.
