The Grand Finale : probing the origin of Saturn s aurorae with HST observations simultaneous to Cassini polar measurements With the increasing tilting of Saturn s north pole toward the Earth, HST has the opportunity to achieve unprecedented views of the entire northern aurorae at high spatial and temporal resolution. Such observations will shed light onto the auroral processes specific to the northern magnetosphere (the planet s magnetic dipole is offset toward the north) and compared to past similar observations of the southern aurorae. Furthermore, the Cassini spacecraft is about to start its last mission phase - the grand finale - with polar orbits around the planet, sampling the unexplored auroral regions at low altitude, before ultimately impacting the atmosphere. This proposal aims at taking advantage of this unique occasion to identify the acceleration processes responsible for Saturn's aurorae with HST remote observations combined with Cassini local measurements. HST images and spectra of the northern aurorae will primarily be scheduled when Cassini samples in situ the plasma conditions within the auroral regions, to assess fundamental plasma physics processes including acceleration, wave-particle interaction and energy/momentum transfer. Several HST orbits will also be coordinated with Cassini remote imaging of the southern aurorae to achieve a simultaneous view of both hemispheres and investigate magnetic (non-)conjugacy. Observations of Saturn's northern UV aurorae while Cassini observes the southern aurorae. The time windows are critical and are listed in order of preference. Visits 01-03 and 04-06 are grouped within 11h to observe auroral dynamics over a fraction of a planetary rotation. Each visit consists of a single STIS orbit, made of a unique long exposure time-tagged FUV-MAMA image. The SrF2 filter is used to minimise geocoronal contamination. Time-tag mode is used with a buffer of 100s. Past observations show that the maximum global count rate remains <10000 cts/sec. Orient ranges are intended to avoid the repeller wire shadow and dark current across the northern polar region.
