Observations started at twilight. The observations began at zenith distance = 76 deg. The sun altitude is -16.0 deg. The galactic latitude b = 33 deg., longitude l = 312 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3136874 We obtain a following upper limits.
