The Cassini CIRS instrument continues its observations of the thermal emission from the active "tiger stripe" fractures at the south pole of Enceladus. On August 13th 2010, on orbit 136, the "E11" Enceladus encounter provided a particularly favorable geometry for remote sensing of the south pole, and yielded some of the most detailed observations of tiger stripe thermal emission of the entire mission. Maps of 6.7 - 16.7 !m thermal emission from one of the brightest regions of Damascus Sulcus reveal large variations in brightness along the length of the fracture with a peak near the source of Plume 2 [7]. The emission from the brightest region is close to a blackbody, with best-fit temperatures in the range 167 - 185 K, depending on the exact wavelength range and spatial subset of the data that is fitted. Lower-temperature radiation is also seen from the flanks of the sulcus.
