POS TARG + PATTERN warning - We don't have a pattern in 16074. POS TARG is used in Quad frames in order to minimize slew amount and allow same guide stars for the whole orbit.Cyclones as the Dominant Source Regions for Jovian LightningLightning on Jupiter is associated with moist convection, spanning the water cloud level near 5 bar up to the tops of the ammonia clouds near 0.5 bar. Moist convection has been identified as a heat transport process able to transport most of Jupiter's internal heat to the cloud tops. The combination of Juno lightning measurements and HST photometric imaging for cloud structure will test the possibility that cyclonic vortices are the location of most of the moist convective activity.
The Juno spacecraft has measured the spatial distribution of lightning flashes, showing that flash rates are highly variable with latitude, with a northern flash rate about 2x higher than in the south. This published result was based on data from the first third of the Juno mission (2016-2017), but a recent discovery announced in October 2019 suggests a shift in the latitudinal distribution in the second third of the mission (2017-2018).
We propose to cover Juno passes in April, June, and September 2020, using one HST orbit of WFC3 imaging for each pass. Along the spacecraft path, the HST observations will determine cloud structure proximity to cyclonic vortices at each latitude. Juno itself cannot provide the necessary context, because its visible-light camera lacks the filters to constrain cloud depth, and it has limited spatial coverage due to pointing constraints and data volume. By characterizing the fraction of lightning events closely associated with cyclonic vortices, we will be able to control for this factor in the search for actual temporal variation in the distribution of lightning with latitude.One orbit on each of three dates (see table). The objective is to time orbits so that the PJ longitude is close to disk center, and the observation time is close to the perijove time. After analyzing SAA timing and guide star placement, we have found that the best timing windows are one Jupiter rotation after the PJ26 pass, and one Jupiter rotation before the PJ27 and PJ29 passes.

For each perijove, the optimized timing is encoded in BETWEEN timing requirements.
Filters in the APT file are ordered to maximize science return, assuming full visibility windows. For reduced visibility windows, frames are listed here from high to low priority (although this list may be circumvented if particular problems are found due to guide star availability and multiple UVIS quandrants):

POS TARG [-15, +15] is used on all the 2K2D-SUB exposures to postion them closer to UVIS center and maintain guide stars.
We have approval for BLADE=A for 4-sec exposures (F631N and F502N) to minimize shutter-blade jitter.The Team Expertise section is not required for Mid-Cycle proposals.Solar SystemPlanets and Planet Formation3falsefalsetruefalsefalsefalsefalseAVAILABLESOLAR SYSTEMYESPLANETJupiter atmosphereSTD=JUPITEREARTHWFC3/UVISImagingNoNoFQ727NWFC3/UVISImagingNoNoFQ889NWFC3/UVISImagingNoNoFQ750NWFC3/UVISImagingNoNoF631NWFC3/UVISImagingNoNoF225WWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF395NWFC3/UVISImagingNoNoF343NWFC3/UVISImagingNoNoFQ727NWFC3/UVISImagingNoNoFQ889NWFC3/UVISImagingNoNoFQ750NWFC3/UVISImagingNoNoF631NWFC3/UVISImagingNoNoF225WWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF395NWFC3/UVISImagingNoNoF343NWFC3/UVISImagingNoNoFQ727NWFC3/UVISImagingNoNoFQ889NWFC3/UVISImagingNoNoFQ750NWFC3/UVISImagingNoNoF631NWFC3/UVISImagingNoNoF225WWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF395NWFC3/UVISImagingNoNoF343NUsing ephemeris for target 16074-26-JUPITERephemeris data for target 16074-26-JUPITER does not cover planning interval.
