GCNC\n13913), we triggered the 3.5m CAHA telescope (+ Omega 2000) at the\nGerman-Spanish Calar Alto Observatory. Observations (900s each) were taken\nin the YJHK-bands, starting at 18:05 UT (i.e. 13 hr post burst). At the\nposition of the X-ray afterglow (Evans et al. GCNC 13918), we do not\ndetect a near-IR countepart in any band, particularly down to H = 20.5.\"\n\nThis message can be quoted.\n\n[GCN OPS NOTE(30oct12):  Per author's request, PF was added to the author list.]",
