This study will help understand minor species chemistry related to dynamics in Jupiter's stratosphere/upper troposphere. 19JUDARKSIDE Observe equatorial Lyman-alpha on Jupiter's darkside to determine long-term changes as a function of System III longitude from charged particle impact upon thermospheric hydrogen. 19GUAURORA01 Ganymede aurora observations of possible H I Lyman-alpha and O I (1356) emissions. We will attempt to detect the Ganymede aurora in conjunction with SSI and NIMS in a mini-campaign 19JUFTL10301 AWG feature campaign to study the role and abundance of water in Jupiter's atmosphere, particularly in regions associated with storms and lighting. 19TV19MANS01 EUV/UVS map of Io torus midnight ansa to determine morphological changes in torus over the timescale of several years. 19JUAURORA_N Northern Jupiter aurora observations of Lyman-alpha near the 180 (N) longitude. We will attempt to capture the Io fluxtube footprint (IFT) to understand long-term magnetosphere and Jovian upper atmosphere interaction. We will also attempt to obtain the first NUV spectrum of the Jovian aurora. 19HV_STARCAL: Star cross calibration using Lyman-alpha for EUV on Sirius and the sky background. ************************** W.
