The observations began at zenith distance = 18 deg. The sun altitude is -35.0 deg. The galactic latitude b = -13 deg., longitude l = 236 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2690291 We obtain a following upper limits.
