We propose to image the UV (H and H2) aurorae of Uranus with STIS and ACS instruments near next opposition with a two-fold objective. We first aim at investigating the current, poorly known, magnetospheric configuration in which a diversity of UV aurorae, probing various acceleration mechanisms, is expected to co-exist. The observations will be carefully scheduled to sample variable solar wind conditions and all planetary longitudes to asses the solar wind/magnetosphere interaction. The aurorae will then be accurately fitted by model auroral ovals to retrieve the position of the magnetic poles. This reference will then be used, on the one hand to further constrain the inner rotation rate and the associated SIII longitude system and, on the other hand to analyze planned coordinated observations of the planet by JWST in the NIR and by XMM-Newton at X-ray wavelengths. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal requests a sequence of 9 STIS imaging orbits distributed in three groups scheduled close to next opposition on 31 Oct. 2020. They will be divided in three groups of three orbits which will sample variable solar wind conditions predicted enough in advance. Two groups will sample intervals of high dynamic pressures (compressed state of the magnetosphere) and one group will sample quiet solar wind (relaxed state of the magnetosphere). The methodology employed to predict solar wind conditions at Uranus will be identical to that developed for past similar GO programs. The proposed observtions will consist of 9 STIS orbits, with TIME-TAG imaging using the clear and SRF2 filters. ------------------------------------------------------------------------------------ 17214( 15) - 14-Nov-2022 13:25:12 - [ 2] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: URANUS ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: PLANET PLANET URANUS ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 STD=URANUS ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = 5.73 +/- 0.5 Ephemeris Center: EARTH ------------------------------------------------------------------------------------------------------------------------------------ 17214( 15) - 14-Nov-2022 13:25:12 - [ 3] Visit: 01 (URANUS) Visit Requirements: BETWEEN 01-SEP-2022:00:00:00 AND 31-OCT-2022:00:00:00; VISIBILITY INTERVAL 51.5 M On Hold Comments: Additional Comments: The filter and integration times are similar to those used in proposal 14036.
