MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Blagoveschensk was pointed to the  GRB140206A (Lien et. al GCN 
15784 , Gotz et. al GCN 15784)  2h 16m (8153 s) after trigger time at 
2014-02-06 09:33:13 UT directly after sunset. On our first sets we found 
optical transient Oksanen et. al. GCN 15786.

The coordinate is:

RA= 09h 41m 20.21s
DEC= +66d 45m 37.7s
ERROR= 0.5 arcsec
Mag=18.5 +- 0.25m

Our unfiltered magnitude is calibrated by USNO
B1.0 catalog  by a parity 0.8R + 0.2B.
