About This Round
For PJ16 the spacecraft will be oriented such that the camera field of view is pointed towards the groundtrack - the swath of the cloudtops the spacecraft is flying over - rather than oriented with the high gain antenna pointed at earth (the more typical attitude, designed to optimize the gravity interior structure experiment). This means that the images will contain more Jupiter, less sky, and the illumination will be better.

PJ16 also occurs when the earth is close to being behind the sun as seen from Juno. Downlink of data to the earth is always minimal at these times because the proximity to the sun means we must reduce the data rate to earth or the link will be noisy.

For these two reasons we are focusing our limited data volume on the perijove pass and we will not be taking pictures on approach or departure.

As we approach the north pole from the night side of Jupiter we will take a series of images with varying amounts of time-delayed-integration, to see what is the best choice between seeing into the shadows at the north pole, and avoiding saturation of more southerly latitudes. This pass we hope to see where circumpolar cyclone #7 has moved, and interestingly whether some other atmospheric feature has pushed it there.

The series of northern hemisphere images will include a nice image of White Spot Z. The spacecraft reaches perijove at a latitude of ~19 deg North as the orbit continues to evolve.

We look forward to seeing more mesoscale waves near the equator. In the southern hemisphere we expect to get a good look at Oval BA.

As the spacecraft departs we will collect a 40 min timelapse sequence of the south pole.
