The observations began at zenith distance = 79 deg. The sun altitude is -61.0 deg. The galactic latitude b = 40 deg., longitude l = 231 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3036088 We obtain a following upper limits.
