In order to gain information on Europa's plume occurrence or variability, it is important to unambiguously detect and effectively constrain the H2O occurence and plume properties during each observation. Localized abundance of well-detectable salt related trace species like sodium might provide additional means to detect plume activity and constrain ocean composition and/or ice grain formation within the plume venting process. In our medium-size program we exploit the long-slit spectral imaging capabilities of STIS, which uniquely provide both spectral and spatial identification of local plumerelated signals. Using three different STIS spectral modes and two WFC3 narrow band filters, we globally constrain far-uv, near-uv and visible auroral emissions as well as Ly-alpha absorption from plumes in sunlight, eclipse and Jupiter transit. Due to the different observing modes and targeted geometries, the proposed 22 visits will be scheduled uniformly over the ~6-months Jupiter observing season and each visit will be carried 3

4 Proposal (STScI Edit Number: 42, Created: Thursday, August 2, 218 2:1:45 PM EST) - Overview out during optimized observing conditions maximizing the sensitvity of HST to plume signals. OBRVING DESCRIPTION Our program focuses on observations of auroral emissions produced by electron impact on H2O to identify water plumes at Europa with multiple setups in and out of eclipse and in and out of transit. We apply new modes to target visible auroral emissions in eclipse and near-uv aurora pointing off the limb of Europa. The setups are chosen to avoid interference with surface-reflected sunlight in both cases. A few sets of trial observations obtained using director's discretionary time are used to inform about these innovative modes. All aurora observations are to be scheduled when Europa crosses the plasma sheet to maximize auroral excitation. In addition, we propose to schedule Ly-alpha transit observation visits jointly with aurora observations as well as jointly with the FUV imaging mode from Sparks et al. 4

Proposal 15419, NUV off-limb before opp (5), completed Thu Aug 2 19:1:46 GMT 218 Diagnostic Status: Warning Scientific Instruments: STIS/NUV-MAMA, STIS/CCD Special Requirements: SCHED 4%; ORIENT 298D TO 3 D; BETWEEN 19-MAR-218::: AND 17-APR-218::: Comments: This visit required precise off-limb targeting. Visit The slit should be parallel to the equator, i.e. have an angle of 9 degrees with respect to the polar axis (slighltly differeny from original planing where we wanted the slit at a 6 deg angle w.r.t. the polar axis). This is constrained through the ORIENT keyword, which is calcualted using the approximate angle between Europa North and Celestial North before opposition (-16 deg) and the offset of the STIS detector y axis from the telescope U3 axis (45.3 deg). ORIENT = 9 deg + 45 deg - 16 deg = 119 deg. Before opposition, the available ORIENT range is near 27, so this means +18 deg: ORIENT = 117 deg + 18 deg ~ 299 deg. Furthermore, the slit needs to be shifted from the center of the disk to Europa south along the dispersion (x) axis such that the slit center has an offsets of.2 arcec (1st exposure) and.4 arcsec (2nd exposure) to the limb of the disk. At the currently requested observing period between 19 March and 17 April 218, Europa's angular diameter is between.9 and.96 arcsec. Thus, the radius is about.465 arcsec. Therefore, the POS TARG keyword is set to X = =.665. UPDATE POS TARG when exact window is selected! Diagnostics Solar System Targets Exposures Update: Observation on 218 March 28: JupiterNorth to CelestialNorth angle CCW: deg. The available orient range is (u3) 264 to 33 degrees. Europa radius:.43 ". Offset for exposure 1: X = =.63. Offset for exposure 2: X = =.83. The calculations give the shift of the slit w.r.t. the target, but the POS TARG X keyword must then be negative, because it gives the position of the target w.r.t. the slit instead. So X = -.63 and -.83, respectively.
