MASTER OT J071845.44+194439.4 discovery - new OT with ampl>6m (no VIZIER data)
AT2020ae
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 07h 18m 45.44s +19d 44m 39.4s on 2020-01-01.06525 UT.
The OT unfiltered magnitude is 16.5m(mlim=19.6).
The OT is seen in 6 images. There is no minor planet at this place.
We have reference image on 2016-11-09.18647 UT with unfiltered mlim=20.8m.
Taking into account Palomar and PnSTARRs' m_limits in history (VIZIER database) the amplitude of current outburst is more then 6m.
Spectral observations are required.
The discovery and reference images are available at:
