We find a flux ratio anomaly of A2/A1= 0.93 +/- 0.02 for the quasar images A1 and A2. When combined with the 11.7 micron measurements from Minezaki et al. (2009), the A2/A1 flux ratio is nearly 5-sigma from the expected ratio for a model based on the two visible lens galaxies. The mid-IR flux ratio anomaly can be explained by a satellite (substructure), 0.3\" Northeast of image A2, as can the detailed VLBI structures of the jet produced b","authors_text":"Chelsea L MacLeod, Christopher S.
