The AGILE repointing followed a significant flaring activity of this blazar, as detected in the optical and X-ray bands. AGILE subsequently detected the source in the gamma-ray energy band during the early phase of the observation (see ATel #1160).Gamma RayAGNTransientshttp://adsabs.harvard.edu/abs/2007ATel.1167....1B2007ATel.1167....1B
