Abstract
The inner 3 x 4 pc of the Galaxy have been imaged in the (Ne II) (12.8-micron) line with 2 arcsec and 30 km/s resolution. The morphology of much of the ionized gas can be explained by a one-armed linear spiral. The kinematics of the gas along the spiral can be modeled by approximately circular orbits with a nearly Keplerian rotation curve, requiring a central mass of 2 +/- 0.5 x 10 exp 6 solar mass. Several possible origins are suggested for the spiral.
