MASTER-SAAO robotic telescope (MASTER-Net: http://observ.pereplet.ru
Lipunov et al.,2010,Advances in Astronomy,2010,30L)
automatically was pointed to Swift GRB 200210A (Laha et al. GCN 29444,Ttrigger 02:00:27UT)
at 2021-02-10 02:03:54UT (first exposition),
but the alert altitude was 07 degrees (under the roof, so there is no stars at first images)
and roses above the roof only 27min after trigger time (Lipunov et al. GCN 29445).
MASTER auto-detection system found optical afterglow
MASTER OT J173104.99+143945.9 (discovered by Swift-UVOT, GCN 29444).
We observed it untill sunrise (MASTER automatical programm of Swift alert observations).
The reduction of MASTER wide field and very wide field cameras images will be continued.
