Observations started at twilight. The observations began at zenith distance = 68 deg. The sun altitude is -11.1 deg. The galactic latitude b = -4 deg., longitude l = 68 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1848048 We obtain a following upper limits.
