The observations began at zenith distance = 77 deg. The sun altitude is -17.2 deg. The galactic latitude b = -84 deg., longitude l = 164 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2668531 We obtain a following upper limits.
