MASTER OT J101326.12-413942.9 discovery -new OT, ampl>6m, no VIZIER
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 10h 13m 26.12s -41d 39m 42.9s on 2018-10-05.10326 UT.
The OT unfiltered magnitude is 15.9m (mlim=19.3).
The OT is seen in 9 images (02:25:28.955-02:40:29.78UT). There is no minor planet at this place.
We have reference image on 2015-03-18.89258 UT with unfiltered mlim=20.3m, on 2018-04-02 21:44:58 with mlim=19.4m (MASTER-SAAO), on 2018-09-24 09:22:51 with mlim=17.9(MASTER-OAFA).
There is no any sources in VIZIER database, it means 22m POSS limit and more then 6mag of current outburst amplitude
Spectral observations are required.
