- Аннотация: MASTER OT J104822.39-453356.8 detection - dwarf nova outburst, ampl>5.8m MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 10h 48m 22.39s -45d 33m 56.8s on 2018-07-09.07564 UT. The OT unfiltered magnitude is 15.2m (mlim=18.6m). The OT is seen in 2 inspect images. There is no minor planet at this place. We have reference image without OT on 2017-12-08.18951 UT with 18.2 unfiltered magnitude limit (MASTER-OAFA), on 2016-05-02 19:04:07UT with mlim=21.0(MASTER-SAAO) . so the amplitude of current outburst is more then 5.8m There is USNO-B1 star with previous outburst in 1982.5 . Spectral observations are required. The discovery and referenceimages are available at http://master.sai.msu.ru/static/OT/104822.39-453356.8.png
