    Abstract

    Maps of the dark cloud ESO 210-6A and the associated NIR source HH 46/47 were constructed using IRAS data. The 60/100 micron color temperature distribution in the cloud shows that the temperature in the cloud ranges from 20 to 40 K, with the maximum temperature at the position of the NIR source. On the other hand, the 12/25 micron color temperature distribution shows temperatures ranging from 200 to 400 K, and exhibits a minimum at the position of the NIR source. Such an anticorrelation between 12/25 micron and 60/100 micron temperature distributions extends to all parts of the cloud. The dust mass and the FIR luminosity of the ESO 210-6A dark cloud, derived from the 60-micron and 100-micron fluxes, were found to be about 0.08 solar mass and 44 solar luminosities, respectively
