The observations began at zenith distance = 83 deg. The sun altitude is -44.1 deg. The galactic latitude b = -14 deg., longitude l = 203 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2671089 We obtain a following upper limits.
