The observations began at zenith distance = 78 deg. The sun altitude is -63.8 deg. The galactic latitude b = -34 deg., longitude l = 255 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2028549 We obtain a following upper limits.
