About This Round
The orbit petal continues to evolve toward midnight at apojove so Juno approaches Jupiter from the night side in the north. Fully illuminated images are acquired pole-to-pole but images close to perijove capture just a sliver of the crescent. North polar images are higher resolution on each pass. The evolution of the orbit also causes southward motion of apojove, which means that as the spacecraft recedes from perijove the south pole is in view for a long time, but at lower resolution every pass. Io's shadow crosses Jupiter and we are right over it!
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 image sequence begins and ends with lightning search images inbound and outbound on the dark side. Images in the northern hemisphere are taken close together in time as the geometry changes rapidly. In the southern hemisphere the geometry changes slowly and images are collected at a leisurely pace.
