Research Abstract

We planned to perform a new photometric observation of asteroid Itokawa in order to quantitatively measure the change in its spin rate due to the YORP effect. Although our observation had been scheduled to be performed using Subaru telescope, the observing data could not have been acquired owing to bad weather. We will aim at the next apparition and carry on the data analysis for the other objects.
