- Аннотация: MASTER OT J141757.08-451601.3 discovery - 6.5mag amplitude outburst MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 14h 17m 57.08s -45d 16m 01.3s on 2019-04-03.02571 UT. The OT magnitude in 'R' filter is 15.5m (mlim=18.3). The OT is seen in 2 images (opened survey mode of MASTER observations). There is no minor planet at this place. We have reference image on 2019-03-02.05494 UT with 'R' filter 18.6m, the nearest in time image is on 2019-03-18 00:14:35 with mlim_R=18.0, on 2016-03-12 00:45:36UT with unfiltered mlim=20.6 (MASTER_W=0.2B+0.8R calibrated by thousands USNO-B1 field stars). There is no any sources in VIZIER database, it means 22m POSS limits in history and more then 6.5magnitude of current outburst amplitude. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/141757.08-451601.3.png
