MASTER OT J111725.04+293457.6 - possible Supernova

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 11h 17m 25.04s +29d 34m 57.6s on 2014-04-03.80535 UT. The OT unfiltered magnitude is 17.5m (limit 19.4m). The OT is seen in 6 images. There is no minor planet at this place. We have reference image without OT on 2013-12-30.96519 UT with unfiltered magnitude limit 19.1m. Sum of six 60-sec unfiltered exposures by MASTER-Kislovodsk on 2014 Apr. 03.751-03.805 UT is uploaded to http://master.sai.msu.ru/static/OT/J111725+293457-MASTER-Kislovodsk.jpg

The new object is located 0.6" east and 0.2" north of the center of galaxy SDSS J111724.99+293457.4 (g=20.09 r=19.83 i=19.56) = GALEX J111724.9+293457 (FUV=21.51 NUV=21.41). Spectral confirmation is required. Discovery and reference images are available at: http://master.sai.msu.ru/static/OT/111725.04293457.6.png

MASTER OT J161143.92+194436.5 - possible Supernova

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 16h 11m 43.92s +19d 44m 36.5s on 2014-04-06.96306 UT. The OT unfiltered magnitude is 19.3m (limit 19.7m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2013-12-26.13295 UT with unfiltered magnitude limit 19.6m. Sum of six 60-sec unfiltered exposures by MASTER-Kislovodsk on 2014 Apr. 06.917-06.963 UT is uploaded to http://master.sai.msu.ru/static/OT/J161143+194436-MASTER-Kislovodsk.jpg

The new object is located 1" east and 0" north of the center of galaxy SDSS J161143.85+194436.5 (g=21.77 r=21.26 i=20.86). Spectral confirmation is required. Discovery and reference images are available at: http://master.sai.msu.ru/static/OT/161143.92194436.5.png
