If this event was observed by Konus-WIND or NEAR, a smaller error box can probably be derived. Our 8x600s images cover the entire error box with two overlapping pointings. The effective integration time varies over the area of the error box. From visual inspection of the combined image, we do not find any objects which are not present on the Digital Sky Survey 2 red plate. This object, by comparison between the two frames, seems to be fading.
Deeper analysis is in progress.
The object reported by Bartolini et al. The total exposure time was 10 minutes for each epoch. Seeing was 1.3 and 1.7 arcsec on the two epochs, respectively. The object reported by Bartolini et al. This is consistent with the findings by Pedersen et al.
