Hi again, The TLE I used to prepare for my observation proved to be very reliable. It can be used by anyone for the final moments of powered flight. I just don't understand why NASA keeps on publishing incorrect MECO TLE every time. Here is the TLE published by NASA before launch (MM 18.151 !!!) : SHUTTLE 1 00123U 08071.32561054 .00020000 00000-0 70000-3 0 9002 2 00123 51.6370 161.2897 0408284 168.8587 192.2088 18.15107113 23 And here's the one I created using state vector and VEC2TLE : STS-123 MECO 1 00123U 08009A 8071.27686343 .01000000 88387-3 95600-4 0 15 2 00123 51.6370 161.6017 0132607 348.6512 69.1979 16.48649198 18 Of course, for most of the ascent we have to use the Ted's Excel spreadsheet since the TLE is only good for the portion of flight just before MECO. From my place the shuttle reached a 4 degree elevation. So it can be seen from more deeply inland or farther north if you have an unobstructed view and clear weather.
