Post-equinox Uranus aurorae during a strong magnetosphere-solar wind shock interaction HST recently succeeded to re-detect Uranus aurorae with imaging and spectroscopy in 2011 (sampling solar wind shock interactions) and 2012 (sampling two planetary rotations), when the planet was near-equinox. The detected emissions (4 positive detections to date) both differ from the Uranian aurorae detected by Voyager 2 in 1986, at solstice, from those detected in a single HST image in 1998, and from other well-known planetary aurorae. Their characteristics suggested a different control of solar wind and planetary rotation on auroral processes than that known at other planets. The morphology of the aurorae seemingly evolves along the Uranian orbital revolution as a function of the topology of open/closed field lines imposed by the tilt between the magnetic axis and the solar wind flow. Uranus passed equinox 7 years ago and now gradually reaches an intermediate equinox-to-solstice configuration which deserves to be fully analyzed. The purpose of this proposal is to enlarge the set of positive detections and to sample the auroral processes and associated magnetospheric dynamics at relevant timescales (1/3 rotation to ~1 week/~10 rotations) in the present equinox-to-solstice configuration. To increase the probability of auroral brightening triggered by magnetospheric compressions, observations will again be scheduled during active solar wind conditions predicted for late Oct. 2014, with a validated methodology used for previous observations. Additional objectives include the extended study of airglow, the characterization of the extended neutral corona and the investigation of the atmospheric hydrocarbon photochemistry. Uranus will be observed through a sequence of 7 HST orbits distributed along approximately a week sampling the arrival at Uranus of an interplanetary shock, so far predicted to reach the planet on 31 Oct. 2014. The arrival time of the interplanetary shock will be checked (and further refined) by iterative runs of robust MHD propagation codes. The proposed observations will consist of 6 STIS orbits, with TIME-TAG imaging using the clear and SRF2 filters, and 1 COS orbit, with TIME-TAG spectroscopy using the FUV G140L gratings. STIS will track the reflected solar emission, airglow and auroral emissions. COS will additionally attempts to detect atmospheric absorption or emission by hydrocarbons. We request the COS orbit to imediatly follow or preceed one STIS orbit, to help the analysis of COS spectra with STIS images.
