dc.description2D spectroscopy of Q0957+561 in the CIII]lambda1909 emission line reveals a rich variety of spatially extended features. We point out: (i) a blueshifted region apparently connecting the A and B compact images; (ii) an almost complete arc in the West side which fits well with the infrared arc detected by the Hubble Space Telescope and (iii) traces of extended emission in the East side which could be the fragments of a larger arc-shaped structure. These features should be explained by the current lens models.
