The Air Force Phillips Laboratory has been pursuing an active near-Earth object (NEO) observing program for several years. To date, the focus of this program has been to highly automate the positional observational analysis in support of the Minor Planet Center and for follow-up of discoveries by the Near-Earth Asteroid Tracking (NEAT), Spacewatch, and other search efforts. Several hundred new discoveries have been made in the course of these follow-up observations. The program is being expanded to include the collection of photometric lightcurves to support NEO characterization studies including pole and shape determination. Most recently, these observations have concentrated on NEO 1991 VH, an Apollo asteroid with a double period suggesting that it may be a binary object. We present the results from these observations.
