The burst given in GCN 12503 should be GRB111029A, 
but not  GRB 110929A. We apologize for this typo. 

"We began to observe GRB 111029A (Troja  al., GCN 12498)
with Xinglong TNT telescope at 10:35:49 (UT), about 51 min  after 
the burst.  15 R-band images were obtained under a bad seeing. 
No new source was detected in the combined R band image within 
the errorbox of XRT position. The upper limit was estimated 
to be about 19.6 mag derived from USNO B1.0 R2 mag.
