Building connections: Juno and STIS contemporaneous observations of Jupiter's magnetosphere and auroras

0 Assigned ID: 569 ----- Attempting Submission 1 (Fri Mar 06 17:01:58 GMT 2020) ----- HST Phase I Proposal 569 successfully submitted. Receipt: # 569-1 Out of the initial 25 requested orbits, the panel only attributed 5 to this campaign. We thus optimized the observation dates to maximize the scientific output (made of three separte goals) with a restricted number of observations. There will be 1) one orbit dedicated to simulataneous measurements of the northern aurora with HST as Juno will operate its in situ instruments in the northern hemisphere (ideally during Juno perijove 30 -PJ30), 2) one orbit dedicated to simulataneous measurements of the northern aurora with HST as Juno will operate its in situ and remote sensing instruments in the southern hemisphere (ideally during Juno PJ36) and 3) a sequence of three orbits (ideally one every jovian rotation (~10 hours)) when Juno will cross the magnetospheric current sheet (ideally during PJ35). For each of these three goals, alternative dates are possible, which are only marginally less favourable. 1290557227 ----- Attempting Submission 1 (Tue Jun 30 11:13:32 GMT 2020) ----- Building connections: Juno and STIS contemporaneous observations of Jupiter's magnetosphere and auroras Juno and HST form a powerful and unique combination to unravel the processes coupling the Jovian magnetosphere to its atmosphere through its auroras. As an example, context images of the UV auroras offered by HST help making sense out of the Juno in situ measurements and disentangle spatial from temporal effects. As Juno's orbit evolves, new challenges and opportunities emerge during cycle 28. In particular, Juno will fly at lower and lower altitudes over the north pole, potentially accessing the deepest part of the region where the charged particle causing the aurora get accelerated. Unfortunately, Juno's remote sensing instruments will be too close to Jupiter and Juno will fly to fast in the North to offer global images of the auroras associated with the in situ wave, field and particle measurements. Only HST is able to provide the spatially resolved UV images critical to properly interpret the data. Furthermore, Juno will cross the magnetic equator closer and closer to Jupiter, exploring new areas where some key physics for the dynamics of the plasma in Jupiter's magnetosphere takes place. Simultaneous global images with the STIS instrument will allow the identification and classification of the structures crossed by Juno as well as estimates of their spatial range and temporal variability. In return, Juno will unravel the plasma processes giving rise to the auroral feature imaged by HST. Finally, we will take advantage of a rare opportunity for truly simultaneous imaging of the two polar auroras of Jupiter when Juno is in the southern hemisphere to shed light on the mystery of the conjugate auroral flares in the polar-most region of the Jovian auroras. Out of the initial 25 requested orbits, the panel only attributed 5 to this campaign. We thus optimized the observation dates to maximize the scientific output (made of three separte goals) with a restricted number of observations. There will be 1) one orbit dedicated to simulataneous measurements of the northern aurora with HST as Juno will operate its in situ instruments in the northern hemisphere (ideally during Juno perijove 30 -PJ30), 2) one orbit dedicated to simulataneous measurements of the northern aurora with HST as Juno will operate its in situ and remote sensing instruments in the southern hemisphere (ideally during Juno PJ36) and 3) a sequence of three orbits (ideally one every jovian rotation (~10 hours)) when Juno will cross the magnetospheric current sheet (ideally during PJ35). For each of these three goals, alternative dates are possible, which are only marginally less favourable. In practice, the observation strategy for these 5 orbits is similar to the one carried out in past programs dedicated to imaging Jupiter's aurora with STIS (e.g. 15638 lead by Co-I Denis Grodent): Observations of Jupiter's aurora will be obtained using the STIS/FUV-MAMA instrument using the F25SRF2 filter, in order to observe the H2 Lyman and Werner emissions whilst removing contamination from the geocoronal Lyman-alpha. Jupiter will be positioned 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. We will obtain ~2400 s time-tagged exposures, from which images integrated over smaller intervals (e.g. 10-100 s) will be extracted. POS_ANG parameters will be provided in a timely manner. They depend on the exact observing time (which determines the orientation of the aurora on the planetary disk) and ORIENT angle and are such that STIS MAMA repeller wire does not cross the auroral region. Similar observations can be and have been carried out with gyro restrictions in the past. These limitations on the orientation of the detector only require some fine-tuning of the poiting to limit the contribution of the planetary disk to the total count rate. The investigators on this proposal have unparalleled depth of experience studying the auroras of the outer planets, through HST observations, theoretical modeling, and in situ spacecraft data analysis. The PI has experience in analyzing very large numbers of Jupiter HST auroral images and spectra. He has a long history of studying the detailed morphology of Jupiter and Saturn's variable auroras. In particular, this team efficiently planned and analysed a large set of 248 orbits, in parallel with Juno instruments and in coordination with other space-based and Earth-based observatories. The lead investigators of the UVS, JIRAM, JADE, JEDI, MAG, and Waves Juno instruments are among the proposing team, which will ensure full and immediate comparison of these data with those obtained simultaneously with HST. Altogether, the investigators of the present program were involved in more than 100 other successful HST programs and contributed to about 500 peer reviewed papers on Jupiter and its moons (source: NASA/ADS). They have significant experience of the software and techniques required to analyze UV HST images and spectra. They are also used to combine HST data with data from other spacecraft (Juno, Galileo, Cassini, New Horizons, Hisaki, ...). All investigators have excellent track records of producing world-class, high-impact publications using HST data. The team gained outreach expertise with large program GO-14634 and GO-15638 to convert STIS time tagged series into preview movies showing the auroral region as it appears in STIS' field of view, as well as its polar projection. These movies will be immediately released on a public YouTube channel and on an institutional web page: www.youtube.com/channel/UCRNZgJOwKbNOw3pDPHUzXPQ www.lpap.uliege.be/cms/c_3478756/en/lpap-hst-campaign Solar System Astronomy 0 false false true false false false false SUPPORTED SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ30 STD=JUPITER TYPE=POS_ANGLE,RAD=26,ANG=-13,REF=NORTH NOT OCC OF PJ30-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35a STD=JUPITER TYPE=POS_ANGLE,RAD=25,ANG=-32,REF=NORTH NOT OCC OF PJ35A-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 116 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35b STD=JUPITER TYPE=POS_ANGLE,RAD=26,ANG=-22,REF=NORTH NOT OCC OF PJ35B-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35b STD=JUPITER TYPE=POS_ANGLE,RAD=26,ANG=-17,REF=NORTH NOT OCC OF PJ35B-NORTH-AURORA-COPY BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35b STD=JUPITER TYPE=POS_ANGLE,RAD=25,ANG=-30,REF=NORTH NOT OCC OF PJ36B-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35_c STD=JUPITER TYPE=POS_ANGLE,RAD=26,ANG=-18,REF=NORTH NOT OCC OF PJ35C-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ35_c STD=JUPITER TYPE=POS_ANGLE,RAD=27,ANG=-25,REF=NORTH NOT OCC OF PJ38-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH SOLAR SYSTEM PLANET Jupiter_aurora_North_PJ36 STD=JUPITER TYPE=POS_ANGLE,RAD=26,ANG=-10,REF=NORTH NOT OCC OF PJ36-NORTH-AURORA BY JUPITER FROM EARTH, CML OF JUPITER FROM EARTH BETWEEN 120 220 EARTH STIS/FUV-MAMA Imaging No No F25SRF2 STIS/FUV-MAMA Imaging No No F25SRF2 STIS/FUV-MAMA Imaging No No F25SRF2 STIS/FUV-MAMA Imaging No No F25SRF2 STIS/FUV-MAMA Imaging No No F25SRF2 1628102894610 The scheduling data was generated by CASM 28.2.
