Observations started at twilight. The observations began at zenith distance = 59 deg. The sun altitude is -13.8 deg. The galactic latitude b = -21 deg., longitude l = 66 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1843611 We obtain a following upper limits.
