Kulkarni (Caltech) report:\n\nWe have imaged a ca. 13 arcmin radius field around the WXM localization of\nGRB031026 (Butler et al. GCN 2429), using the Max-Planck Millimeter\nBolometer array at the IRAM 30m telescope. We do not find any source\nwith a 250 GHz (1.2 mm) flux density >16 mJy (4 sigma upper limit)\nwithin 10 armin of this position. The observations were conducted\nbetween UT Oct 10.9 and Nov 2.2. Further details and maps can be found\nat http://www.mpifr-bonn.mpg.de/staff/bertoldi/projects/grb031026\n\nWe wish to thank the IRAM staff for their flexibile scheduling of the\ntelescope, which made these observations possible.\n\nThis result may be cited.",
