Good morning, Lucille and I were able to take a point each during the 04:29 UTC pass on July 27. 31702 07 027B 1747 G 20070727042933050 37 25 0005333+171124 38 31702 07 027B 1747 G 20070727043138220 37 25 0154004+291500 19 I used Starry Night Pro Plus v6 to give her a course on satellite tracking and she could practice her timing with the software as it gives a realistic view of the stars along with the movement of satellites in real time in forward or backward mode, a very interesting feature. She could also familiarize herself with the area of the sky where she was waiting for the satellite. I'm very confident in her data since I was able to get a view of the area using another pair of binos (we got three) while she made her click on the stopwatch. I compared the observations with the following elset from Ted : 1 70000U 07207.18968729 .00000022 00000-0 10000-4 0 05 2 70000 63.3139 288.1043 0117651 196.6169 163.1025 14.17689016 00 and this one from Pierre created from his data (arc 22.2-26.2 jul) : 1 70003U 07207.4717579 .00000030 00000-0 10000-4 0 08 2 70003 63.2001 287.1807 0121662 196.5944 163.0077 14.17699927 08 My graphical analysis (for what it's worth) shows Pierre's elset to be right on time within 0.2 sec. But Ted's trajectory is more accurate in position (if we don't mind the timing). Both elset showed a slightly lower trajectory in elevation than observed. I guess that with tonight's observations orbital data will be more accurate. Bad weather is coming so I won't be able to observe for a couple of days.
