J. Moss et al., GCN 29849) errorbox 13 sec after notice time and 47 sec after trigger time at 2021-04-21 00:28:17 UT, with upper limit up to 17.1 mag. The observations began at zenith distance = 54 deg. The sun altitude is -30.5 deg. The galactic latitude b = 5 deg., longitude l = 210 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1597889 We obtain a following upper limits.
