I DO recall that one of the issues of STAR WARS INSIDER(the official fan magazine)had a picture from the Coruscant skyshot showing and circling/highlighting which of the passing ships was the Enterprise. The issue, I believe, came out in 2000 or 2001 after the first series of rumors about the Enterprise's presence started getting circulated inside the SW and TREK fan communities.
Don't quote that as science,
though. I just remember the picture showing the Enterprise was in *a* issue of the fan magazine around the time the first prequel was about to come out on DVD. I guess anyone who has old copies of the INSIDER from that time can go looking for it in the Q&A sections.
