The only modificiation being the POS-TAR of imaging observations. All tools have been run, and the warning on the BOT tool has been checked with the CS. HST STIS/ACS observations of the aurorae of Uranus during active solar wind conditions The UV aurorae of Uranus, suspected in IUE observations (1982-1986), were only unambiguously identified during the Voyager 2 flyby (1986). Their peculiar properties relate to the atypical magnetosphere of Uranus, which is characteristic of ice giants. In contrast with the solstice configuration prevailing in the 1980s, that only allowed the northern magnetic pole to be visible from Earth, the situation is now radically different and near-equinoctial conditions allow views of both northern (N) and southern (S) poles transiting across the visible disc, implying a dynamic magnetospheric configuration that has never been studied. We therefore propose to re-attempt to observe the UV aurorae of Uranus with HST spectroscopic (STIS) and imaging (ACS) measurements. We will maximize the probability of detection by scheduling observations of Uranus during a solar wind shock interaction, known to activate auroral activity at other planets. Observations will be distributed over 14 days, centered on the predicted arrival time, and sampling all longitudes. They will characterize the UV aurorae, determine their brightness (and infer the energy of precipitating electrons), their location and their temporal variability up to half a solar rotation. Importantly, it will also permit us to retrieve the rotational phase of the planet and update the rotation period (17.24h). Observations during an interplanetary shock and comparisons with Voyager 2 and previous unsucessful HST observations will finally provide the first insights into the sun/magnetosphere interaction, and highlight its difference with the interaction at the other known magnetospheres.
Uranus will be observed through a sequence of 16 HST orbits distributed along 14 days (half a solar rotation), scheduled just after Uranus opposition (26 Sept. 2011) around the planned arrival time of an interplanetary shock. These observations will be scheduled more than 1 month in advance in the HST observing program. The arrival time of the interplanetary shock will be accurately predicted from robust MHD propagation codes. HST orbits will be distributed 14 days with 2 groups of orbits. (1) 10 orbits will scan a core window covering 7 days (9.5 Uranian periods) centered on the predicted arrival time, among which 8 orbits will be placed every ~1.2 planetary periods, and 2 orbits will be added close to the center of the interval with a spacing of ~0.3 planetary periods. (2) 6 orbits will scan 7 days out of the core window (orange), spaced by ~1.8 periods. The total sequence will thus provide a continuous sampling of a full planetary rotation and a regular coverage of all Uranian longitudes over half a solar rotation. To take advantage of both the STIS spectroscopic capability and of the ACS SBC imaging high sensitivity, the HST orbits will be alternately dedicated to STIS measurements (images and spectra) and to ACS SBC observations (images only). If one instrument is not operating normally, observations can be done with the other one. The spectra will be acquired by STIS with the G140L gratings and large slit of 2x52 arcsec. The images will provide the spatial distribution of auroral Lyα (121.6 nm) and H2 Lyman bands (115-165 nm). Images will be obtained by STIS and ACS SBC, using MAMA and F115LP (clear), as well as FSRF2 and F125LP (Lyα blocker) filters. To minimize contamination by geocoronal background brightness at Lyα, clear images will be taken during the portion of the orbit when HST is in shadow, and filtered images otherwise. In addition, geocoronal contribution will be minimized by observing close to opposition. This program requires observing Uranus (a weak FUV source) within a 14 days-long window centered on on the time t0 of enhanced solar wind activity at Uranus, that will be predicted by the observers >1 month in advance. Additionally, this window will be scheduled as close as possible from opposition, within 1 month to minimize the geocoronal background. This program will be conducted in combination with other observations (see proposal).
