Cline, on behalf of the NEAR GRB team,\nreport:\n\nWe have obtained a refined position for this burst using higher time\nresolution data, and adding the data of the NEAR spacecraft.  This\nresults in a true error box, as opposed to just a triangulation\nannulus.  This error box is consistent with that obtained from the\nintersection of the Ulysses-BATSE annulus with the RXTE error circle,\nand therefore confirms that the fading X-ray source is indeed related\nto the GRB, but in this preliminary analysis, it does not reduce \nits size.\n\nThus the refined error box (area ~30 sq. arcmin.) is defined by the new \nUlysses-BATSE annulus and the RXTE error circle.  The corners are at:\n\n  RA(2000)                Dec(2000)\n11 h 54 m 33 s      -26 o 50 ' 59 \"\n11 h 54 m 56 s      -26 o 40 ' 07 \"\n11 h 54 m 24 s      -26 o 49 ' 16 \"\n11 h 54 m 45 s      -26 o 39 ' 36 \"\n\nReductions in the widths of the annuli of the order of a factor\nof two or more will be possible.
