GCNC 8112, Barthelmy et al. GCNC 8113), we have\nobserved the field starting on Aug 23 (since 01:45 UT) with different\ntelescopes/instruments on Spanish ground-based observatories: 0.6m\nBOOTES-2 (Z-band), 1.2m Mercator Telescope (Ic-band) and 2.5m Isaac Newton\nTelescope (r' & i' -bands). No optical counterpart within the reported\nSwift XRT error box is detected on the first r'-band image obtained on Aug\n23, 02:49 UT (high\nairmass, limiting magnitude r'~21.5). We notice that some of the later\nimages overlap in time with the large gamma-ray flare reported by Krimm et\nal. (GCN 8120) with null detection as a preliminary result once we have\ninspected\nby eye the whole BAT error box. Further analysis is on going\".\n\n\nThis message can be quoted.\n\n[GCN OPS NOTE(23aug08): Per author's request, \"J. Corral\" was replaced with\n\"J. M. Corral-Santana\" in the author list.]",
