The observations began at zenith distance = 34 deg. The sun altitude is -44.8 deg.MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )discovered OT source at (RA, Dec) = 20h 53m 57.98s -53d 08m 20.3s on 2021-07-14.35751 UT with fast decay typical for GRB OT light curve.The OT magnitude (unfiltered)at 08:52:10UT(ttrigger=07:56:33) 16.1m (mlim=18.7).We have reference image on 2016-07-30.14890 UT with unfiltered 20.3m.Spectral observations of host galaxy (presents in VIZIER) are required.
