Extensive pre-encounter, space-, and ground-based observations are being performed to prepare for the flyby in July 2010. The aim of this article is to accurately characterize the photometric properties of this asteroid over a broad spectral range from the ultraviolet to the near-infrared and to search for evidence of surface inhomogeneities. Description: The asteroid was imaged on 2 and 3 January 2007 with the Narrow Angle Camera (NAC) of the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) during the cruise phase of the Rosetta spacecraft. The geometric conditions were such that the aspect angle was 44° (i.e., mid-northern latitudes) and the phase angle 22.4°. Lutetia was continuously monitored over 14.3h, thus exceeding one rotational period and a half, with twelve filters whose spectral coverage extended from 271 to 986nm. An accurate photometric calibration was obtained from the observations of a solar analog star, 16 Cyg B. File Summary:
