MASTER OT J171438.08-585400.2 detection - outburst with more then 7m amplitude
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 17h 14m 38.08s -58d 54m 00.2s on 2019-05-30.25356 UT.
The OT unfiltered magnitude is 15.0m (mlim=17.8m).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference image without OT on 2017-07-21.18039 UT with unfiltered mlim=19.4m.
There is no USNO-B1 sources, it means 22m in history (limit) and mre then 7m of currentutburst amplitude
Spectral observations are required.
