About This Round
The spacecraft orientation for this perijove pass was non-standard. The spacecraft was rotated to allow the MicroWave Radiometer to observe orthogonal to the routine data collection attitude. This orthogonal orientation allows the sun to pass through JunoCam's field of view, which could cause damage if JunoCam inadvertently imaged the sun. For this reason the decision was made to delay powering on the camera until after the return to a nominal spacecraft attitude.

JunoCam was powered on 45 min after closest approach and took the first image at PJ+50 min. By this time only the southern hemisphere is in view. Since there was plenty of data volume we chose to return all the images with lossless data compression. South polar movies alternate time-delayed integration settings to be optimal for the disk (TDI 1 or 3) and for the terminator (TDI 3 and 6). Two additional images bracket the pole with TDI 9, knowing that the limb would be saturated. Two sequences of methane images are collected with minimal time separation to allow stacking of the frames.

The final hours outbound are looking at the dark side of Jupiter, so we will do our first search for lightning looking at the southern hemisphere.
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.
