We present observations of NGC1333 from SCUBA-2 on JCMT, observed as a JCMTGould Belt Survey pilot project during the shared risk campaign when the firstof four arrays was installed at each of 450 and 850 microns. Temperature mapsare derived from 450 micron and 850 micron ratios under the assumption ofconstant dust opacity spectral index beta=1.8. Temperatures indicate that thedust in the northern (IRAS 6/8) region of NGC1333 is hot, 20-40 K, due toheating by the B star SVS3, other young stars in the IR/optically visiblecluster, and embedded protostars. Other luminous protostars are also identifiedby temperature rises at the 17" resolution of the ratio maps (0.02 pc assuminga distance of 250 pc for Perseus). The extensive heating raises the possibilitythat the radiative feedback may lead to increased masses for the nextgeneration of stars.
