We present Herschel observations of the isolated, low-mass star-forming Bokglobule CB244. It contains two cold sources, a low-mass Class 0 protostar and astarless core, which is likely to be prestellar in nature, separated by 90arcsec (~ 18000 AU). The Herschel data sample the peak of the Planck spectrumfor these sources, and are therefore ideal for dust-temperature and columndensity modeling. With these data and a near-IR extinction map, the MIPS 70micron mosaic, the SCUBA 850 micron map, and the IRAM 1.3 mm map, we model thedust-temperature and column density of CB244 and present the first measureddust-temperature map of an entire star-forming molecular cloud. We find thatthe column-averaged dust-temperature near the protostar is ~ 17.7 K, while forthe starless core it is ~ 10.6K, and that the effect of external heating causesthe cloud dust-temperature to rise to ~ 17 K where the hydrogen column densitydrops below 10^21 cm^-2. The total hydrogen mass of CB244 (assuming a distanceof 200 pc) is 15 +/- 5 M_sun. The mass of the protostellar core is 1.6 +/- 0.1M_sun and the mass of the starless core is 5 +/- 2 M_sun, indicating that ~ 45%of the mass in the globule is participating in the star-formation process.
