MASTER OT J233626.71+082501.4 - possible supernova

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 23h 36m 26.71s +08d 25m 01.4s on 2014-09-02.91001 UT. The OT unfiltered magnitude is 18.8m (limit 20.0m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2011-12-13.66122 UT with unfiltered magnitude limit 20.0m.

The new object is located 3" east and 10" south of the nucleus of galaxy SDSS J233626.51+082511.6 (g=17.35 r=16.84 i=16.55) = GALEX J233626.4+082512 (FUV=19.69 NUV=19.41) with unknown redshift.

Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/233626.71082501.4.png

MASTER OT J000253.08+130551.1 - possible supernova in PGC 1422807

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 00h 02m 53.08s +13d 05m 51.1s on 2014-09-03.91119 UT. The OT unfiltered magnitude is 18.0m (limit 20.1m). The OT is seen in 6 images. There is no minor planet at this place. We have reference image without OT on 2011-08-30.98838 UT with unfiltered magnitude limit 20.1m.

The new object is located 12" east and 5.5" north of the center of galaxy PGC 1422807 = SDSS J000252.19+130547.1 (g=16.66 r=16.20 i=15.93) with unknown redshift.

Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/000253.08130551.1.png
