Here the other drafts of north polar PJ16 images.
The north polar images have been designed to obtain good data of the northern circum polar cyclones (CPCs), and in order to get data as close to the pole as possible.
We hope to be able to retrieve information about the dynamics of the CPCs.
Due to solar conjunction, the amount of data for PJ16 is limited. The instruments of the spacecraft were looking close to the ground track, without the HGA antenna pointing to Earth during flyby. For JunoCam, the overall focus is on good close-up images. Only few approach and departure images have been taken, actually no approach or departure sequence.
