Observations started at twilight. The observations began at zenith distance = 55 deg. The sun altitude is -15.4 deg. The galactic latitude b = 0 deg., longitude l = 58 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2116623 We obtain a following upper limits.
