Weiss (MPIfR Bonn) report:\n\nWe observed the host galaxy of GRB 050904 (GCN 3910) at redshift z=6.29\n(GCN 3937), RA 00:54:50.83, Dec +14:05:10 (J2000), with the\nMax-Planck-Millimeter Bolometer (MAMBO-2) array at the IRAM 30-m telescope\non 27 February 2006 and 03 March 2006, and obtained a non-detection of\n\n   S_nu(250 GHz,1.20mm) = -0.76 +/- 0.45 mJy  \n\n(1 sigma error), i.e. a 3 sigma upper flux density limit of 1.35 mJy. The\nMAMBO-2 bolometer detectors cover 210-290 GHz (half power). The host\ngalaxy of GRB 050904 is well within our 10.7 arcsec FWHM beam.\n\nThis message may be cited.",
