Lacrosse 3 and Uranus
The pass was a very low pass however, the satellite did not come higher than 25 degrees in the sky. This made it difficult, and I only managed to capture it on two images when the satellite was just above rooftop level, in a "gap" between two roofs. On the first image it appears from behind the roof (endpoint measurable), on the second it disappears behind the roof (startpoint measurable).
When astrometrically measuring the images, I noted a relatively bright star near the end of the trail that I could not identify. It was also on the 2nd image. The star was bright enough that it should appear in the database AstroRecord uses, and my Sky Atlas didn't show a star there either. So...?
As I was measuring the image anyway, I decided to measure the star to get a position for it. it yielded (18 Jan 2009, 17:49:12.3 UTC):
RA 350.855, dec -4.751
= 23h 23m 25.2s, -4 45' 03.6" (2000.0)
I checked AstPlot: it did not show a star nor an asteroid on that position. I downloaded a NEAT image of the region: again, no star on that position....
By that time, I was thinking: Oi, what's this?!? A nova?!?
Then I got a hunch. I started up MICA, and obtained accurate positions for Uranus and Neptune. And yes, there it was:
Astrometric Positions Mean Equator and Equinox of J2000.0

So, I accidently "re-discovered" Uranus... 228 years too late... :-p
