MASTER II robotic double telescope (FOW=2x4 square degrees,
http://observ.pereplet.ru) located in Tunka was observed the
GRB120129A (S. Golenetskii et al., GCN Circ
12904) IPN triangulation error-box using 9 diffent fields.
Observations proceeded since 2012-01-30 20:50 to 2012-01-30 22:50 i.e
aprox. 1.3 days after grbtime.
On our images we haven`t found an optical transient
within IPN error-box (S. Golenetskii et al., GCN Circ 12904).
Unfiltred upper limit is 18.5 on each image.
There is a one strange OT MASTER022229.64+523924.9
which seen only at one image.

2012-01-30 22:50:52.423 02h 22m 29.64s , +52d 39m 24s.9 15.37
The object is not seen on images given after (10 hours) and before (1
hour) detection time.

Our very wide fiels cameras (FOW=2x420 square degrees) synchronously
with GRB have covered area directly under the errors-box.
