MASTER OT J023717.57+071736.1 discovery - PSN in 46.2"E,43.9"S from the center of NGC 997
AT 2020nej
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 02h 37m 17.57s +07d 17m 36.1s on 2020-06-22.15671 UT.
The OT unfiltered magnitude is 17.0m
(mlim=18.9).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image on 2018-08-15.12858 UT with unfiltered mlim= 20.7m.
Spectral observations are required.
