MASTER OT J001247.38+335337.6 detection - BZQJ0012+335 optical flare, ampl~(1.8-4)mag
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 00h 12m 47.38s +33d 53m 37.6s on 2019-02-21.72328 UT.
The OT unfiltered magnitude is 16.2m (limit 17.8m).
The OT is seen in 8 images. There is no minor planet at this place.
We have reference image without OT on 2014-10-14.85262 UT with unfiltered magnitude limit 20.2m.
There is marginally seen OT in MASTER-Amur database (2018-11-17 09:55:41UT) with m <~ mlim=18.0 (unfiltered). So the amplitude of current flare can be ampl~(1.8-4)mag
Observations in different wavelenght are required.
