MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 19h 50m 04.70s +52d 38m 56.2s on 2017-02-26.26975 UT during inspection of G275404.

The OT unfiltered magnitude is ~ 19.0m (m_limit=19.5m).

This PSN is in 2.4W,2.6N of disc galaxy PGC2420186 (http://leda.univ-lyon1.fr/ledacat.cgi?PGC2420186 )

This PSN is seen in 3 images. There is no minor planet at this place.

We have reference image without OT on 2016-05-07.15047 UT with unfiltered magnitude limit 20.1m.

Spectral observations are required.
