[23.04] HST Imaging of the Seyfert 2 Galaxy NGC 2110

Hubble Space Telescope images of the Seyfert 2 Galaxy NGC 2110 in the emission lines of [OIII]$\lambda$5007 and H$\alpha$ will be presented. The dominant line emission is associated with a strongly curved, narrow 1$''$ (200 pc) long feature emanating from the nucleus to the north and northeast. The jet-like radio source shows some spatial correlation with this curved feature, but the off-nucleus 6cm peaks are in regions of weak emission lines. On a larger scale, there is a `S'-shaped distribution of ionized gas (seen best in H$\alpha$ ) extending $\sim$ 4 $''$ north and south of the nucleus. Ground-based kinematical data suggests this larger scale gas represents a warped rotating disk. There is evidence from a color map for an unresolved region of very strong reddening at the location of the nucleus.
