- Аннотация: MASTER OT J135330.69-543614.8 discovery - possibly CV outburst, ampl>4.5m MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 13h 53m 30.69s -54d 36m 14.8s on 2019-02-04.03872 UT. The OT unfiltered magnitude is 17.5m (mlim=18.7). The OT is seen in 4 images. There is no minor planet at this place. We have reference image on 2017-03-03.05799 UT with unfiltered mlim= 19.6m, the nearest in time mlim=18.5 on 2019-01-21 02:15:56UT. There is no optical sources inside 3" in VIZIER database, it means 22m POSS limit (there is marginally seen object in POSS images). There is Gaia source in 3.06" with Gmag=19.9, but its offset is too much . Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/135330.69-543614.8.png
