Abstract

We present observational data of the double lensed quasar UM673 obtained with the 1.5-m telescope of the Maidanak Observatory and the 1.3-m SMARTS telescope at CTIO between 2006 and 2010. We combine these data with our previously published observational data of UM673 to measure the time delay between the UM673 images. We also analyze the time evolution of the flux ratio between the UM673 images.
