We present new 12, 25, 60, and 100 micron HIRES-processed IRAS images of the nearby Serpens star-forming cloud core at FWHM resolutions of ~ 30"-10'. We use HIRES-processed point-source models of the IRAS emission to derive new flux values and flux upper limits for all the protostellar candidates in the Serpens core. Our fluxes (and flux upper limits) determine the spectral energy distributions (SED's) necessary to derive the dust temperature, circumstellar mass, bolometric luminosity, and evolutionary status of each protostellar candidate. Remarkably, we find that all five sources: FIRS1, SMM4, S68N, SMM2, and SMM3 studied by Hurt, Barsony & Wootten (1996) share the defining characteristics of Class 0 protostars, the short-lived (a few X 10^4 yr) earliest observable protostellar stage (Andre, Ward-Thompson & Barsony 1993, Barsony 1994).
