— We present results from an observing campaign of 25143 Itokawa performed with the 2.2 m telescope of the University of Hawai'i between November 2000 and September 2001. The main goal of this paper is to determine the absolute magnitude H and the slope parameter G of the phase function with high accuracy for use in determining the geometric albedo of Itokawa. We found a value of H = 19.40 and a value of G = 0.21.
