MASTER OT J110621.77-765447.8 discovery - new OT, ampl more then 4.5m
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 11h 06m 21.77s -76d 54m 47.8s on 2019-03-18.93362UT.
The OT unfiltered magnitude is 17.5m (mlim=19.2).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference images on 2019-03-05 22:20:00UT with mlim=20.2, on 2015-02-25.96255 UT with unfiltered mlim= 20.8m (MASTER W=0.2B+0.8R, calibrated by USNO-B1 B2,R2;B1,R1 thousands field stars).
There is no any known sources in VIZIER database, it means 22m POSS limit in history and more then 4.5m of current outburst amplitude
Spectral observations are required.
