Observations started at twilight. The observations began at zenith distance = 69 deg. The sun altitude is -10.3 deg. The galactic latitude b = -17 deg., longitude l = 351 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2021399 We obtain a following upper limits.
