Vladimir Lipunov reports the discovery of a possible supernova by Alexey Rufanov using MASTER-Kislovodsk robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD) and auto-detection system on the unfiltered survey images (60-sec exposures, limit 19.4m) obtained on 2014-04-03.805 UT. The new object (unfiltered magnitude 17.5) is located at R.A. = 11h17m25s.04, +29o34'57".6 (J2000.0) which is 0.6" east and 0.2" north of the galaxy SDSS J111724.99+293457.4 (rmag=19.8). The object is seen in 6 images. 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 We have reference image without OT on 2013-12-30.965 UT with unfiltered magnitude limit 19.1m. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/111725.04293457.6.png (ref. ATel 6055, http://www.astronomerstelegram.org/?read=6055 )
