I know the first close Io flyby is still a couple of months away but I'm going to go ahead and start up the topic now with a few preview images that the global map from PJ55 into the pixel scale, lighting conditions, and orientation of the highest resolution images that JunoCam would take (illuminated by the sun, there's always a chance for Jupiter-shine images), based on the current reference spk and c-kernel:
This also assumes an image cadence of 1 every other rotation (so 1 per minute). info about the encounter: CODE Perijove Date (UTC) SC Altitude (Io, km) SC Latitude (Io IAU, deg) SC W Longitude (Io IAU, deg) Vinf (Io, km/s) Phase Angle Magnetic Latitude of Io (Jupiter System III, deg) E Longitude of Io (Jupiter System III, deg) True Anomaly of Io (deg) Separation Angle

Preview images using the latest ephemeris and c-kernel. First image according to that kernel has the green frame centered on Io at 2023-Dec-30 08:37:07.177. Preview images are spaced every 2 rotations.
I take it that there are not images prior to C/A/ Looked like there might be some decent imaging at ~19 km/pixel of the anti-Jovian hemisphere. A bit disappointed at the lack of Jupiter-shine images but given what happened in PJ56 I totally understand. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
