dc.descriptionThe four-component gravitational lens CLASS B1608+656 has been monitored with the VLA for two seasons in order to search for time delays between the components. These time delays can be combined with mass models of the lens system to yield a measurement of H_0. The component light curves show significantly different behavior in the two observing seasons. In the first season the light curves have maximum variations of ~5%, while in the second season the components experienced a nearly monotonic ~40% decrease in flux. We present the time delays derived from a joint analysis of the light curves from the two seasons.
