Two overlapping pulses. COMMENTS: Total duration ~40 sec. COMMENTS: Seen above 300 keV. COMMENTS: This GRB was also localized by COMPTEL: RA=104.39, Dec=41.38. COMMENTS: This burst was seen by the SAX-GRBM and -WFC instruments COMMENTS: and localized to RA=105.67, Dec=38.85 (IAUC #6853). COMMENTS: More information about this burst can be found at the GCN URLs: COMMENTS: http://gcn.gsfc.nasa.gov/gcn/gcn_main.html COMMENTS: http://gcn.gsfc.nasa.gov/gcn/batse_grbs.html and COMMENTS: http://gcn.gsfc.nasa.gov/gcn/selected.html and COMMENTS: and the sub-pages therein. This IPN localization is preliminary. The "total width" of the annulus was selected to include all known uncertainties and systematics. The final analysis will reduce this width. All follow-up queries should be addressed to Kevin Hurley (UC Berkeley, khurley@sunspot.ssl.berkeley.edu). The center of the IPN annulus is tabulated below along the segment that intersects the Huntsville error circle. The Distance column is the sky-angle distance between the Huntville location and the sampled position on the arc segment. The position of maximum probability plus the 1-, 2-, & 3-sigma containment probabilities (statistical+systematic) are marked.
