C. Muñoz-Mateos (Univ. Complutense Madrid),\nM. Jelínek and J. Gorosabel (IAA-CSIC),\n\nreport:\n\n\"Following the detection by SWIFT of the short GRB 060801\n(Racusin et al. GCNC 5378, Sato et al. GCN 5381), we have\ntaken R-band frames at the 2.0m Hanle telescope in India\n(+HFOSC) starting on Aug 1.75 UT. Additional BVR-band frames\nhave been taken with the auxiliary port camera at the 3.5m\ntelescope at the German-Spanish Calar Alto Observatory in\nsouth Spain, starting on Aug 1.935 UT. Near the  position of\nthe X-ray afterglow (Racusin et al. GCN 5382), we detect two\nfaint optical sources in the R-band images:\n\nsource A: 14 12 01.8  +16 59 00.5\n\nsource B: 14 12 01.3 +16 58 54.0\n\nwith 1\" accuracy (for the time being).\n\nsource A is at the edge of the XRT error box and brighter than\nsource B and it seems to be constant in brightness over the time\ninterval of our observations. Source B is consistent with the\nXRT error box and there is marginal evidence that source B has\ndeclined in brightness, with R = 22.5 +/- 0.5 (preliminary) in the\n3.5m CAHA images. Further analysis is in progress.\"\n\nThis message can be quoted.\n\n[GCN OPS NOTE(08aug06): By author's request, the spelling of the\nSánchez and J. C. Muñoz-Mateos names were corrected.]",
