Using Pisgah Astronomical Research Institute's (PARI) 26 meter West Radio Telescope, I investigated the velocity structure and overall presence of hydrogen in a region of the supernova remnant HB9 (Green, 2009). This was done by taking spectral data over a 142.5 by 127.5 arc minute grid surrounding the most intense region of hydrogen emission. The spectra were summed under the hydrogen peak to create an overall hydrogen map of the region. Spectra were also divided amongst different frequency channels to model the velocity structure of the hydrogen present in the region. My findings are compared with additional velocity and hydrogen composition maps (Leahy & Roger, 1991).
