VII Zw 403 is a blue compact dwarf galaxy, with one unresolved x-ray source. The galaxy was previously observed with the Very Large Array Radio Telescope in Socorro, New Mexico while in the C and D configurations; the data being analyzed in this paper are from the B-configuration. With these data, we have found some previously unresolved structure in the atomic hydrogen (HI) around an X-ray point source and other regions of the galaxy because of the higher resolution offered by the B-configuration. We are also able to see two differently oriented axes of rotation in the galaxy when the B, C, and D data are combined. One question that still needs to be explored is whether or not the x-ray source is the cause of some or all of the hole-like structure in the northeast section of the HI of the galaxy. This work may also shed light on how blue compact dwarf galaxies undergo starbursts without an obvious instigator.
