MASTER OT J033354.90+680653.8 discovery - PSN in irregular PGC13188
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 33m 54.90s +68d 06m 53.8s on 2018-04-21.89509 UT.
The OT unfiltered magnitude is 16.9m (limit 18.3m).
The OT is seen in 5 images: preliminary (automatic) MASTER photometry:
Date_UT, unfiltered_mag+-0.1
2018-04-21 21:28:56 16.9
2018-04-27 23:02:40 17.4
2018-04-29 20:36:14 17.5
2018-04-29 20:30:22 17.6
We have about hundred reference images without OT since 2010-08-07 17:21:26, for example on 2017-01-28.65648 UT with unfiltered magnitude limit 20.2m.
This OT is in the field of irregular PGC13188 with low surface brightness http://leda.univ-lyon1.fr/ledacat.cgi?o=PGC13188
Spectral observations are required.
