MASTER OT J072556.41+414317.5 - possible Supernova

MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 07h 25m 56.41s +41d 43m 17.5s on 2014-02-24.56277 UT. The OT unfiltered magnitude is 17.6m (limit 18.6m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2012-10-21.70659 UT with unfiltered magnitude limit 19.0m.

The OT is located 12" west and 10" north of the center of galaxy PGC 2185706 = SDSS J072557.53+414309.2 (g=20.20 r=19.74 i=19.56). Spectral confirmation is required. Discovery and reference images are available at: http://master.sai.msu.ru/static/OT/072556.41414317.5.png

MASTER OT J094631.32+363845.0 - possible Supernova

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 09h 46m 31.32s +36d 38m 45.0s on 2014-02-26.76799 UT. The OT unfiltered magnitude is 17.6m (limit 18.6m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2011-03-26.64207 UT with unfiltered magnitude limit 20.2m.

The OT is located 1" east and 1" south of the center of galaxy SDSS J094631.22+363846.1 (g=20.70 r=20.60 i=20.52). Spectral confirmation is required. Discovery and reference images are available at: http://master.sai.msu.ru/static/OT/094631.32363845.0.png
