I had complete cloud free skies b4 astronomical twilight Tuesday when I had a look at 2010 XC15. Skies were pristine and visible in the 13" at 250x high in the east. ST4 says mag 13.5. It seemed brighter but I did not try an estimate using comparison stars.
If it was 8" off in DEC vs Horizons, I was unable to see the error. It was indeed moving at >2'/min and was nicely placed in the eastern sky. It passed just over 3° from M3 and ~30' from 6th mag 3 Boo.
Finally, vindication for me that the software can be massaged to work with these fast moving close passes.
