A single, very clear night, for some time. I came home to late to try for the suspect debris. One position for USA 186, 0.29 degrees offtrack. (relative to 08054.806588 elset) 28888 05 042A 5919 E 20080225201418230 18 25 0323253+491396 47 S 28888 05 042A 5919 E 20080225201405312 18 25 0346447+464279 37 S Position is backed up by a photographic position 13 s earlier, using ObsReduce XY mode, but I didn't time it with the stopwatch. Star A: 03:46:59,7301 +46:37:04,001 (2000.0) Mag 7.769 Star B: 03:46:11,8119 +46:47:51,474 (2000.0) Mag 8.756 Object pixel coordinates = 535.0, 270.0 Star A pixel coordinates = 504.0, 280.0 Star B pixel coordinates = 558.0, 270.0 (Actually Ys were 1000 higher, but I got Error13 from thousands separator!) I was testing our daughter's Canon EOS 400D, with a 75-300 mm f/4.5-5.6 lens I also got the separation of #28095/#28097, but no timing. 28095 03 054A 5919 E 20080225205058000 18 25 0443426+174015 37 S 28097 03 054C 5919 E 20080225205058000 18 25 0438204+183257 37 S Star separations for all three objects about 25', positions accuracy better than 1'? USA 186 was about +3 after shadow exit, +5 in the photo, the NOSS were not visible at 1x (and I didn't catch them in binoculars before shadow entry) I was forced to move the tripod 40m to get a free view, and was too late to steady it before starting the capture, so only the end was measurable.
