MASTER OT J211630.72+273356.9 - CV?
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 21h 16m 30.72s +27d 33m 56.9s on 2018-09-13.74243 UT.
The OT unfiltered magnitude is 18.3m (limit 19.9m).
The OT is seen in 8 images. There is no minor planet at this place.
We have reference image without OT on 2010-10-26.80123 UT with unfiltered magnitude limit 19.6m.
Spectral observations are required.
