It was detected in a single camera, yielding an error box with a length of 1.6 degrees and a width of 4.0 arcminutes. A very coarse comparison of the NEAR and RXTE times gives an annulus which contains, but does not improve upon the ASM error box. This error box may be improved. Due to the bad weather, the limiting magnitude was mag about 18.0. Comparing with Digital Sky Survey 2nd generation R image, no new object has not detected within the error box.
Further observation is planned to be carried out tonight.
The limits are preliminary and based on USNO-A2.0 photometry. Oct.27.46 UT, i.e. 1.9 days after the burst. Refined coordinates will be distributed as soon as the final attitude reconstruction is obtained.
