They docked nearly one hour before your observation. During the period between launch and docking and between undocking and de-orbit, the shuttle makes a number of orbital manoeuvres, so during those periods it is best to rely on NASA's predicted elsets, which take into account all planned manoeuvres. They are on this web page (hit the red icon): http://spaceflight1.nasa.gov/realdata/elements/index.html Also, in a recent post, I offered some comments on how to use this information: http://satobs.org/seesat/Jul-2005/0242.html > BTW : where do i get the schedulle for the docking/undocking A copy of the master flight plan is available here (note that date/time is 4 h behind UTC): http://www.spaceflightnow.com/shuttle/sts114/fdf/sts114plan.html Undocking is scheduled for 2005 Aug 05 at 08:27 UTC. In the next few days, I expect to post information on the prospects for observing the shuttle and ISS in close proximity after undocking.
