GCN \n6305) with the\nANU 1m telescope + WFI at Siding Spring observatory. I images taken Apr \n19.737-19.748  and R images taken at Apr 19.753-19.757  confirm the \nsource of Tristram et al. (GCN 6312) at a position\n\n    RA  (2000):   21:02:49.82\n    DEC(2000):  -31:15:49.3\n\n with a position uncertainty +/- 0.1\" referenced to the UCAC2 catalog.\n\nThe R and I magnitudes are estimate to be ~ I=20.7, R=22.1 referenced to \nthe UCAC2/2Mass star\nlocated at 21:02:59.34 -31:18:13.4 with mag ~I=14.75, R=15.25. This is \nsignificantly fainter than observed by Tristram et al., and suggests \nstrongly that this object is associated with GRB07419B.",
