We present four epochs of ultra narrowband coronographic observations using the Goddard Fabry-Perot instrument on the 3.5m telescope at Apache Point Observatory in New Mexico. We clearly discern three distinct red shifted knots moving away from the star with a radial velocity of 100 km/sec and a proper motion of 100 km/sec. We also discern one blue shifted knot moving with a radial velocity of 300 km/sec and a proper motion of 300 km/sec. We also present STIS G140M long slit observations from July 2000 which show the blue shifted jet in Lyman alpha and doubly ionized silicon (Si III, 1206 A). We also present STIS G750L long slit data from August 1999 which show red shifted oxygen [O I] emission in the knots from the counterjet. These results indicate a higher degree of ionization in the jet than in the counterjet.
