The observations began at zenith distance = 61 deg. The sun altitude is -19.5 deg. The galactic latitude b = 25 deg., longitude l = 141 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3035666 We obtain a following upper limits.
