The focus could have been better I think and at the beginning of the movie the asteroid is just barely visible if at all.
Notice the the varying brightness from the rotation. Period looked to be a bit under 1 minute. Photometry was done and the rotation peroid was determined to be just under 3 minutes. http://britastro.org/baa/content/view/393/2/

So, where was it early on the 20th UT? It took me nearly 2 hours to hunt it down with a ~14 arc minute field. I may have unknowingly found it sooner but during it's rotation it was not really visible at times so might have overlooked it. BMP image is here.
