On July 18, 2010, we attempted to observe the Kuiper Belt Object, Ixion. Its predicted shadow path was off of the earth, but because of uncertainties, there was, at best, a 1 in 1000 chance that the object would pass over our location at Williamstown, MA. In the end, our data shows no evidence of the occultation.
