Comments on the images from Perijove 15 (2018 Sep.7)

Io Images

As we acquire images of Io they will be posted here with approximate geometric information. Images are processed by citizen scientists.

PJ14 Image analysis

On PJ14 the spacecraft orbit continues its evolution, bringing the subspacecraft latitude at perijove northward and the subs/c longitude closer to the subsolar longitude

Perijove 13

At PJ13, as at PJ11, the spacecraft was pointed towards the Sun and Earth so the images of low latitudes were oblique. They included panoramic views of several interesting features.

Perijove 12

• FFRs
• waves
• haze
• GRS
• CPCs

This thread will discuss Perijove-12 images. Perijove 12 was very rewarding: GRS, NN-WS-4, CPCs, FFRs, popup clouds, mesoscale waves, high phase angle observations of hazes, methane band images and an image stack, animations,...

Folded Filamentary Regions (FFR)

• FFRs
• waves
• haze
• cyclones

Short-term observations of FFRs, long-term FFR statistics, attempts of data reduction, and modeling

Circumpolar Cyclones (CPC)

• CPCs
• cyclones

Short- and long-term observation of circum-polar cyclones, together with according interpretations and analysis.

Mesoscale waves
