The burst was\nan untriggered event, and appears to be an X-ray rich GRB with a\nduration of > 80 seconds.\n\nIn the Fregate 8-85 keV band, the statistical significance was 9.8\nsigma. A total of 3724 counts were detected during that interval,\ncorresponding to a fluence of ~6.7 x 10-7 cm-2. The peak flux was\n~1.8 x 10-8 ergs cm-2 s-1 (i.e., ~0.5 x Crab flux), assuming a\nCrab-like spectrum. In the WXM 2-25 keV band, the statistical\nsignificance was 6.9 sigma.\n\nBased on the WXM data, the best fit location for GRB011019 is:\n\nRA = 05h00m05s, Dec = +32o07'39\"\n\nwith a total error radius of 11 arcminutes (90% confidence region).\n\nThe duration in the WXM 2-10 keV band was > 80 s. A total of ~3500\ncounts were detected during that interval.\n\nFurther refinement of the burst localization is in progress.\n\nThis message is quotable.",
