Vladimir Lipunov, David Buckley and Oleg Gress reports that MASTER-SAAO(twin 0.40-m f/2.5reflector + 4Kx4K CCD) auto-detection system dicovered possible supernova source at (RA, Dec) = 14h 10m 23.42s -43d 18m 43.7s on 2015-12-15.06619 UT with unfiltered magnitude(W=0.2B+0.8R calibrated to USNO-B1) m_PSN=14.4m (the limit is 18.7m). This PSN (also known as MASTER OT J141023.42-431843.7, ATEL #8415) is in 17.6W 45N from the center of NGC5483 galaxy and is seen in 3 images . There is no minor planet at this place. E.Gorbovskoy and N.Tiurina report that nothing was visible at this position on the MASTER-SAAO images obtained on 2015-04-26.03615 UT with 19.5 unfiltered magnitude limit. The discovery and reference images are available at http://master.sai.msu.ru/static/OT/141023.42-431843.7.png
