MASTER-ICATE robotic Very Wide Field (http://93.180.27.230:8080/) located
in Argentina was pointed to the area of the Trigger 518853 (Barthelmy et
al., GCN Circ 13166) several minutes before
notice time (due to Swiwt pointing info) and 12.9 min after GRB
time at 2012-03-29 02:34:16.391.
We find OT with Mag= 13.2 (unfiltered red CCD) at
Ra=188.552513 Dec -63.417673
Ra 12:34:12.60 Dec -63:25:03.62
With 25" sec 3-sigma error box.
Thre is 2MASS nonstar object 12340720-6325129 with 1.2 arcsec offset.
That is inside XRT error box.
The absence OT in UVOT data may be connected with very high reddening of
the source by Galactic extinction and distinction in time observations.
The follow up IR observations are requied to chose between CR or
High Energy Transient nature (Evans and Osborne, GCN Circ 13167) of the
event.
The message may be cited.
