The observations began at zenith distance = 62 deg. The sun altitude is -54.1 deg. The galactic latitude b = 51 deg., longitude l = 118 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3099928 We obtain a following upper limits.
