  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.

      Date    time             Ra                Dec         Mag
  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.

A preview of this object  available here

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