The observations began at zenith distance = 65 deg. The sun altitude is -27.0 deg. The galactic latitude b = -32 deg., longitude l = 323 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2332732 We obtain a following upper limits.
