Аннотация:MASTER OT J190519.41+301524.4 was discovered as a optical transient by the Mobile Astronomical System of TElescope-Robots (MASTER) in March, 2014. We report the results of photometric observations of this variable performed at the Lajatico Astronomical Center in June-July, 2015. The light curve shows deep V-shaped eclipses with an amplitude of two magnitudes. The orbital period was determined to be 0.129694d (3.113h). Based on the archival observations and the shape of the orbital curve, we suggest that MASTER OT J190519.41+301524.4 is a new cataclysmic variable of VY Scl type ("anti-nova"), with an inclination angle close to 90 degrees.
