A quarter of century after their discovery by Voyager 2 in 1986, HST sucessfully re-detected Uranus aurorae in 2011 (and also in 1998), providing the first images of these emissions. Overall, they differ from other well-known planetary aurorae, and their characteristics vary at very different timescales, from minutes to decades. These results have provided the first insights on the poorly known Uranian magnetosphere in 26 years, and opened a rich field of investigation, together with a set of open questions. In addition, while solstice conditions prevailed in 1986, Uranus lay close to equinox in 2011, with the S and N magnetic poles alternately facing the Sun every half a rotation. This unique configuration of an asymmetric magnetosphere, extremely variable over a single rotation, had never been investigated before and deserved to be fully analyzed. New observations of the Uranian aurorae are therefore vital for our understanding of planetary magnetospheres, and HST is the only tool able to remotely investigate these emissions. We thus propose to re-observe Uranus with STIS spectro-imaging at next opposition (29 Sept. 2012) over two planetary rotations, in order to enlarge the set of positive detections and to sample the rotational dynamics of auroral processes and magnetosphere/solar wind interaction. To increase the probability of any possible auroral brightening triggered by magnetospheric compressions, observations will be scheduled in advance during active solar wind conditions at Uranus, near the maximum of solar cycle 24. Additional objectives will include the characterization of the extended neutral corona and the spectral response of atmospheric species. 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).
