Markarian 463 is an interacting pair of galaxies with two nuclei separated by four arcseconds. The western nucleus has strong narrow emission lines and is best described as a LINER. The brighter eastern nucleus has a classical Seyfert 2 spectrum in unpolarized light. In polarized light broad permitted lines of a Seyfert 1 appear, revealing a hidden broad-line source {Miller & Goodrich 1990}. Presumably, far from the nucleus reflects or scatters the Seyfert 1 spectrum into our line of sight, polarizing it in the process. A WFPC-1 observation by us showed the Seyfert 2 nucleus was extended and was the origin of a sub-arcsecond optical jet {Uomoto et al. 1993}. The jet was resolved into a handful of hot spots similar to the jets in 3C273 and M87. Unlike those synchrotron jets, however, the Mrk 463 jet is most likely due to a mix of starlight, nebular emission, and reflected Seyfert 1 light. The proposed observations are intended to sort out the spatial details in the jet and nucleus and examine the connection between them.
