PJ24 happened back on 12/26 but the spacecraft was in solar conjunction until around the end of the year and we are just starting to get the data back. With the holidays it may be next week before images start showing up on missionjuno, so stay tuned.

Animation of lens flare and Ganymede moving over CCD from PJ24_02.
Somewhat interesting to me is part of flare in lower left that gets brighter and dimmer, but doesn't change position through the spin.
Attached Image


At closest point in this sequence, Sun is about 2º degrees outside camera field of view.
If Sun were to be imaged by JunoCam it would only be about about 4 pixels across.
Images are displayed at realtime rate, but only cover half of a spin (the other half are just black space).

Dust on lens? Or a reflection of something fixed relative to the lens?

Could be a glint off the solar panels or something on the panel structure. The spacecraft was more or less spinning around the sun line at this time since it was so close to conjunction, so the illumination on the panels wouldn't have changed very much during the spin.
