The observations began at zenith distance = 52 deg. The sun altitude is -48.6 deg. The galactic latitude b = -40 deg., longitude l = 352 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3259527 We obtain a following upper limits.
