During the EM, Juno will cross the equatorial region inside of Ganymede's orbit providing an opportunity to obtain HST auroral images simultaneously with high-resolution in situ observations in the crucial inner equatorial region of Jupiter's magnetosphere, where the key dynamics that drive and shape the magnetosphere originate. The STIS/FUV imaging observations proposed here over Cycles 29-31 will answer a large number of outstanding scientific questions, including: * Do magnetosphere-ionosphere coupling currents drive Jupiter's main auroral emission? * What radial forces govern the structure of Jupiter's magnetosphere? * What is the nature of the interaction between Jupiter and its satellites? * How do Jovian plasma populations relate to low latitude auroral emissions? * How does magnetospheric wave activity influence Jupiter's magnetosphere? * What processes give rise to pulsating high-latitude emissions? This program responds to the UV initiative and is only possible during the Juno EM. These observations cannot be made by Juno UVS and HST is the only observatory capable of making these FUV observations, which will yield high-impact results, and complement and extend the goals of the NASA Juno mission. ------------------------------------------------------------------------------------ Observations Description ------------------------ The timescale of the observations required to address the science goals is governed by the orbit of Juno in the EM and covers HST Cycles 29-31; hence our proposal is for a Long Term program of observations. The EM begins in July 2021 and is scheduled nominally to last until August 2025. The availability of Jupiter from HST during Cycles 29-31 is 1 Oct 2021 - 25 Dec 2021; 18 May 2022 - 31 Jan 23; 25 Jun 2023 - 7 March 2024; and 2 Aug 2024 - 30 Sept 2024, where the 17408( 19) - 27-Oct-2025 17:57:56 - [ 2] last date is the assumed end of Cycle 31. Our observations will be clustered around the perijoves, when Juno is in the critical regions of the magnetosphere as described above. Orbit requests are 18 (Cycle 29), 12 (Cycle 30) and 10 (Cycle 31). The orbit request is governed as follows: the science lies in the temporal domain, i.e. variations in the auroral morphology are compared with changes in the in situ field and plasma observations. It is critical that such variation is captured in order to correlate the multiple data sets, and to determine the response to dynamical processes such as solar wind compression events and changing mass loading rates. We hence will use multiple observations for each science goal to capture the key variability that reveals the dynamics of the system. The timescales are: there are typically two ~3- day solar wind compressions per solar rotation (25 days), so the duty cycle for "disturbed" conditions is around 1/4. Thus observing 8 epochs will yield ~2 disturbed intervals, the minimum required to establish repeatable effects. Changes typically take place over a few days. We hence will observe for 2-4 orbits per interval to determine the short-timescale dynamics and to cover both north and south auroras in order to capture the important physics along the entire flux tube. The exact numbers for each interval have been determined by examination of the number of favourable viewing windows for each of the science goals during the 2-3-day intervals surrounding each perijove. We note that there are ~5 SAA-free orbits per day, such that it is possible to observe at least once per day, as has been done successfully previously. For the flybys we will observe as close as possible to the events within the limits of the SAA.These observations will be obtained using the STIS/FUV-MAMA instrument. Auroral images will be obtained using the F25SRF2 filter, in order to observe the H2 Lyman and Werner emission whilst removing contamination from the geocoronal Lyman-alpha. We will observe both northern and southern auroras; the priority will be observing whilst Juno is in the critical regions, rather than focusing on one hemisphere. Jupiter will be positioned using POS_ANGLE (i.e. RAD and ANG) such that only the auroral region and nearby disc will be in the 25x25" field of view, and thus <1/4 of the detector is filled with the planet. This limits the count rates to ~20, 000 counts/s, well within the limit of 200, 000 counts/s. Observations will be taken in ~3000 s time-tagged exposures, from which images integrated over smaller intervals (e.g. 10-100 s) will be extracted. This setup has been successfully used to observe Jupiter's auroras previously. In the event of STIS not being available, these observations will be obtained with the Solar Blind Channel of the Advanced Camera for Surveys, which in practice yields lower signal to noise than STIS owing to its red leak. In the past, Jupiter observations have been successfully obtained in both 2-gyro and 3-gyro mode. In 2-gyro mode we would remove any roll constraints and we would request our orbit during the interval when Jupiter is available. ------------------------------------------------------------------------------------ 17408( 19) - 27-Oct-2025 17:57:56 - [ 3] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: JUPITER-AURORA-JUNOEM-1 ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: PLANET PLANET JUPITER ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 STD=JUPITER TYPE=POS_ANGLE, RAD=25, ANG=10, REF=NORTH ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS CML OF JUPITER FROM EARTH BETWEEN 115 220, NOT OCC OF JUPITER-AURORA-JUNOEM-1 BY JUPITER FROM EARTH ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = -2.5 +/- 0.5 Unless stated, values are for the northern hemisphere.
