Hi Jim, Excellent! Would you have a time (to the second if possible) of the near zenith pass? (Can you also calibrate camera time [photo a time source]) This will help in working out how much the TLEs have drifted by. I think if we can get this, we can tune up the TLE prediction (and not have to wait for space-track).
