Price (IfA, Hawaii) report on behalf\nof a larger collaboration:\n\nWe observed the position of GRB 070520B with the MAGNUM telescope + MIPS\ndual-beam imager in R and J bands, at a mean observation time of 12.69\nhours after the BAT trigger (GCN #6425).  We have only inspected the\nJ-band images, since other reports have covered the optical (GCN\n##6442,6447).  We find no afterglow within the XRT error circle to a\nlimit of J = 20.1 mag.\n\nThis message may be cited.",
