We present preliminary results of a Chandra observation of the south rim of the galactic supernova remnant (SNR) G266.2-1.2. G266.2-1.2 (also known as "Vela Junior'' and RX J0852-4622) is an apparently young SNR along the line of sight to the Vela SNR. The X-ray spectrum of G266.2-1.2 is dominated by non-thermal emission from the shell of the SNR. This Chandra observation resolves the structure of the nonthermal filament and also explores the morphology of a diffuse feature which is apparently over-abundant in O, Ne, and Mg. We will compare this high-resolution image to the nonthermal filament in the NW rim already observed by Chandra. We will determine the upstream and downstream scale widths of the filament from the image and determine the cut-off frequency of the synchrotron emission from the spectra. The image of the thermal emission will be compared to other known fragments of ejecta in the Vela SNR.
