MASTER OT J113634.88+362411.6 discovery - short OT
MASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 11h 36m 34.88s +36d 24m 11.6s on 2019-04-03 17:51:29.991 UT.
The OT is seen in 2 survey images from 3 ones in this night:
Date, T_start_UT(exposition was 60s) unfiltered_magnitude
2019-04-03 17:53:01UT m_OT=16.9+-0.1
2019-04-03 17:51:29UT m_OT=17.9+-0.1
2019-04-03 17:50:01UT mlim=19.6 (no OT)
There is no minor planet at this place.
We have reference image without OT on 2014-03-24 21:49:05UT with unfiltered mlim=20.3.
There is a part of spiral of NGC3755 at this place (not a star like source as it is presented in VIZIER, see DSS/SDSS/PanSTARRS images ) .
Spectral observations are required.
The discovery and reference images are presented here
