These wide and fast propagating interplanetary shocks were directed toward the Earth, Uranus and Neptune which currently orbit at comparable solar longitudes. The first CME reached Earth on Sept. 7 and triggered a severe geomagnetic storm and intense aurora (Kp index = 8) for a couple of days. Previous successful HST observations revealed that the Uranian aurorae observed near equinox respond to powerful solar wind conditions, while Neptune's aurorae (never observed yet with HST) are expected to respond at least similarly, if not (much) more. By numerically propagating near-Earth solar wind measurements with MHD models, we predict the arrival of the first shock at Uranus around 1st Oct. and at Neptune around 1st Nov, with unusually large pressure amplitudes (0.025 and 0.015 nPa resp.) never sampled yet. These extreme active solar wind conditions and ideal solar system configuration brings a unique chance to HST to both catch Uranus aurorae under an intriguing equinox-to-solstice magnetospheric geometry and detect those of Neptune in a frame of comparative planetology. 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.
