| Abstract: | We have analyzed the simultaneous G Band, Ca~{\ec{ii}}~K, Fe~{\sc{i}} 5576~{\AA}, and vector magnetic field data, with the Diffraction Limited Spectro-Polarimeter (DLSP), taken from the Dunn Solar Telescope (DST) at the Sacramento Peak observatory, Sunspot, NM, USA. The main motivation for this analysis is to identify and track the Bright Points (BPs) from the photospheric heights to the chromospheric layers. The vector magnetic fields derived from the high resolution Stokes profiles of the BPs and the velocity maps generated from H$\alpha$ and Fe~{\sc{i}} 5576~{\AA} are discussed in this study. Most of the BPs were found to be located in the downflow regions and the flows seen in the BPs are of jet-like character where higher atmospheric layers show lower velocities compared to the lower atmospheric layers. The morphology of the bright points will also be addressed in this presentation. |
