Recent HST images of galaxies selected by the Galaxy Zoo reveal complicated subarcsecond structures which can only be resolved with HST, including loops, filaments and misaligned ionization cones which provide important diagnostics the radiative history of these AGNs and their impact on the surrounding galactic medium. With spatially resolved spectroscopy of the extended EELRs in these objects, we intend to probe QSO shutdown and AGN feedback on timescales shorter than possible through any other method. The emission line structure on spatial scales accessible only to HST provides evidence for recent transition from a radiative state to a kinematic, radio-dominated mode on timescales far shorter than would be expected from simple scaling of stellar-mass X-ray binaries (Done & Gierlinski, 2005). HST spectroscopy of this sample is therefore necessary, as it effectively provides the only known way to study the small-scale narrow-line features revealed by our HST imaging program. We are using STIS G430L and G750M/L (depending upon expected target brightness) to measure the strengths of extended narrow emission line structures in three fading AGN at low redshift (z~0.03-0.05) at good spatial resolution. In particular, we have chosen four sightlines which trace likely expanding kinematic outflows, ionized cross sections of differentially precessing gas, and strong dust lanes. We will be examining a wide variety of emission lines as indicators of gas density, the ionization parameter, and gas kinematics. Our sightlines (chosen based on pre-existing HST narrow-line images in H-alpha and [O III]) are as follows: In NGC 5972 and SDSS J2201 (2MASX-J22014163+1151237), we are targeting sub-arcsecond bubbles or outflows perpendicular to the main ionization cones. Each of these targets has one sightline. In UGC 7342, we have two sightlines. One is along the main filamentary extended [O III] structure. The other is along the perpendicular dust lane. In all cases, we are using the STIS CCD with 52x0.2 arcsec slit. We will acquire each target using the F28x50LP long-pass filter, with point-source acquisition on the HST continuum peak of the galactic nucleus. From there, we will slew to an offset target, chosen for the ability to observe large cross-sections of the most interesting narrow-line spatial features at the widest possible range of orientation angles. The orientation angle constraints are therefore chosen to observe these emission line features (as chosen from HST imaging in H-alpha and [O III]). A 180-degree rotation is acceptable. NGC 5972 is relatively bright and can be observed in one orbit per grating (G430L, G750M). Each grating for this target requires CR-SPLIT=3 to minimize cosmic ray contamination. SDSS J2201 is faint, requiring 3 orbits per grating (each grating is used in a single exposure with each CR-SPLIT element covering one orbit). For ease of scheduling, we have broken this target into two visits, one each for G430L and G750L. Since we require spatial agreement between spectra, we require the same orientation angle. To prevent observations from having very large time separation, we request a two-month time grouping. UGC 7342 has two sightlines, one along the main gas structure and one along the nuclear dust lane. The gas sightline is more difficult to schedule due to roll constraints but also more scientifically critical. We have relaxed the schedulability percentage of the gas sightline to allow greater schedulability at the cost of orbit length. Each UGC 7342 sightline requires 2 orbits per G430L/G750L grating exposure, with CR-SPLIT=4 for each grating exposure (or 2 sub-exposures per orbit). We prefer not to break this visit into two visits if possible, since the acquisition time for this target is large. For each G750L/M pointing, we have included 2 fringe flat exposures.
