MASTER OT J141401.39-483305.7 discovery - new OT, ampl>6m
AT2020elc

MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 14h 14m 01.39s -48d 33m 05.7s on 2020-03-13.20671 UT.
The OT unfiltered magnitude is 16.4m (mlim=18.2).
The OT is seen in 4 images. There is no minor planet at this place.
This OT is also seen at MASTER-SAAO images on 2020-03-12 21:40:56 with m_OT=16.0
We have reference image on 2017-05-01.26164 UT with unfiltererd mlim=19.3m.
There is no any sources in VIZIER database, it means 22m POSS limit in history and more then 6m of current outburst amplitude.
Spectral observations are required.
The discovery and reference images are available at:
