The purpose of this HST white paper is to demonstrate that it is possible tomonitor Jupiter's polar haze with HST/STIS without breaking the groundscreening limit for bright objects. This demonstration rests on a thoroughsimulation of STIS output from an existing image obtained with HST/WFPC2. It isshown that the STIS NUV-MAMA + F25CIII filter assembly provides a count rateper pixel ~11 times smaller than that obtained for one pixel of WFPC2 WF3 CCD +F218W corresponding filter. This ratio is sufficiently large to cope with thebright solar light scattered by Jupiter's atmosphere, which was a lesserconcern for WFPC2 CCD safety. These STIS images would provide unprecedentedspatial and temporal resolution observations of small-scale stratosphericaerosol structures, possibly associated with Jupiter's complex FUV aurora.
