Labelled red diamonds are the JPL HORIZONS ephemeris for Adelaide.
Times are UT so add 10h30m for CDT.
Looks like it exited your field at about 2115 local.
"Missed it by that much!" ;-)
Note the labelled yellow diamond is where CdC thought it would be using the MPC elements at the standard reference epoch

I generated and entered the elements into Starry Night Pro to create a user defined object. The path was reasonably accurate but the position - timing was also out by 15-25 mins compared to Horizons at different parts of the night. JPL Horizons and the Minor Planet Center Ephemeris service seem to be the gold standard references against which other programs should be checked.
