About This Round
Juno will make a very close pass past Jupiter's large moon Ganymede. Ganymede is the largest moon in the solar system and has its own magnetosphere. This affects weathering of the surface, because charged particles from Jupiter's magnetosphere can travel along open field lines at Ganymede, but are blocked by closed field lines. JunoCam will image approximately one half of one side of Ganymede, as the spacecraft is flying by at ~90 deg phase angle. This is territory that was imaged by Voyager 42 years ago. The closest approach will be at 1044 km, which gives JunoCam images a resolution of 1-3 km/pixel, roughly equivalent to Voyager images. The closest approach will be at lat / lon = 23.7 N / 57.5 W.

About 15 hours later Juno will make its 34th perijove pass by Jupiter. JunoCam images will follow the usual sequence of inbound lightning search, north polar images, perijove swath, south polar images, and outbound departure movie.

Perijove Predict Map
About Perijove Predict Maps

Every perijove pass we have the challenge of predicting where Points of Interest will be as the different zones of the planet have different wind velocities. This map shows our effort to rotate the latitudinal zones with their different wind speeds to predict what will be under the Juno groundtrack.

Winner Selection
The longitude of the PJ pass for PJ34 is almost the same as the longitude of PJ33. This gives us an opportunity to re-image storms after 53 days to study dynamics (if the storms are not moving much relative to the L3 longitude system). We will be looking for Clyde's Spot on the limb. This will be true again at PJ35.
