MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in OAFA was starting survey on the SWIFT GRB171209A error-box
(LaPorte et al. GCN 22213) 44912 sec after notice time and 44965 sec
after trigger time at 2017-12-10 03:15:41 UT. The 5-sigma upper limit on
our single (180s exposure) set is about 19.4-m and 20.0-m on coadd
(3x180 = 540s) image. We not see OT previously reported by Kuin et al. GCN
22221 , Guidorzi et al. GCN 22214 , Kong et al. GCN 22230.

located in SAAO was starting survey on the SWIFT GRB171209A 114607
sec (~ 32 hours) after trigger time at 2017-12-10 03:15:41 UT. The
5-sigma upper limit on our single (180s exposure) set is about 19.4-m
and 20.5-m on coadd (10 x 180 = 1800 s) image. Here we also not see any
OT.
