ABSTRACT: The study of the dust structure around a clump of star forming region sp1 has been performed at +01.9° latitude in the Infrared Science Archive (IRAS) map. The two different fits images of 60 μm and 100 μm are downloaded from sky view virtual observatory and a clump is selected as a study region. The flux densities at different points have been calculated using Aladin software. By analyzing two different Flexible Image Transport System (FITS) images of 60 μm and 100 μm the average temperature is obtained about 34.43 K. The average diameter of this clump is found to have 4.47 pc. The plot of flux densities along diameter is found to have a Gaussian curve. Mass of the clump is found 0.036185 MΘ, whereas the jeans mass for that clump is about 27,896.75 MΘ. Hence from those results, we find that the system is self-iso- lated with radiating dense core and there is no possibility of any star formation in that region.
