- Аннотация: MASTER OT J144402.57-840648.2 discovery - poss. dwarf nova outburst with ampl>5m MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 14h 44m 02.57s -84d 06m 48.2s on 2019-02-19.06146 UT. The OT unfiltered magnitude is 17.0m (mlim=18.0). The OT is seen in 8 images (2019-02-19 01:28:30.675-02:31:33.374UT). There is no minor planet at this place. We have reference image on 2016-12-07.99971 UT with unfiltered mlim= 21.0m. There is no any sources i VIZIER database, it means 22m POSS limit and more then 5mag of current outburst amplitude. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTEROTJ144402.57-840648.2.jpg
