at 00:35:52 UTC on 2021/02/07 from a position consistent with an active Soft 
Gamma Repeater of SGR 1935+2154 (GCN 29363, 29365, 29373, 
29374, 29377, 29381, 29383, 29388, Atel #14359).

The duration of the burst is about 0.1 sec, and its 5 ms peak flux reached about 
130 Crab in the 2-20 keV band.
