MASTER OT J062457.46+311448.7 detection - ampl>5.2m
MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 06h 24m 57.46s +31d 14m 48.7s on 2018-09-23.2474 UT.
The OT unfiltered magnitude is 16.5m (mlimit 19.2m).
The OT is seen in 7 images. There is no minor planet at this place.
We have reference image without OT on 2011-01-30 21:40:55 UT with unfiltered magnitude limit 21.7m.
Spectral observations are required.
The discovery and reference images are available at
