text: I imaged it from 20:51-23:25 UTC using a 0.28m, f/10 SCT and ST9XE CCD camera, and provided astrometry to the Minor Planet Center in time for my data to be used along with astrometric positions provided by several other observatories to fine-tune the orbit so that a Minor Planet Electronic Circular (MPEC) could be issued.
