A systematic search at 100 $\mu$m IRAS (Infrared Asronomical Satellite) survey is performed using Sky View Observatory(http://skyview.gsfc.nasa.gov/).A new arc-like filamentary structure (size $\sim$ 36.35 pc) at R.A. (J2000) = 12$^{h}$29$^{m}$0.33$^{s}$ and Dec. (J2000) = $ $14$^{\circ}$56$^{'}$42.0$^{''}$ is found. This structure is found to be located at the distance of 39 pc north-east from a planetary nebula NGC 4361. In order to find the possible candidate of its origin, we used SIMBAD (http://simbad.u-strasbg.fr) database to locate discrete sources in the region. No other candidate than PN NGC 4361 is observed. In the present work we studied the origin and evolution of this filamentary structure by studying the far infrared flux. For this, ALADIN2.5 software is used for the data reduction. The physical properties of the object and variation of the flux densities are studied. We calculated and studied the temperature and mass profile of the dust.The average temperature of the dust is found to lie in the range 26.26 K to 28.50 K. An offset of $\sim$ 2.5 K suggests the presence of moderate sized silicate dust in the structure. The total mass of the filamentary structure is
