Here we present the results of this A-configuration 8.4 GHz monitoring campaign. The 37 epochs of observations have an average spacing of 3 days. The data have yielded light curves for the four flat-spectrum radio components (components 1, 3, 4 and 6). We find no significant flux density changes in any of the four flat spectrum components.submitted to "Gravitational Lensing: Recent progress and Future Goals", eds: T.Brainerd and C.Kochanek, ASP Conf Series. 2 pages, 1 figure.
