We present an 850 μm image of the young supernova remnant CasA obtained with SCUBA on the JCMT. The morphology of the emission is very similar to that at longer wavelengths, in the radio domain, implying that synchrotron remains the dominant emission mechanism at sub-millimeter wavelengths. The total flux of CasA measured at 850 μm does present a fairly large excess over the flux expected from synchrotron emission alone (as extrapolated from lower frequency data), but it remains unclear whether this excess is real and reects the presence of large amounts of cold dust, or if it is an artifact of the observing technique.
