Southern Aurora, PJ62-136. I'm not sure what to make of it, but I'm leaning strongly towards it being lens glare.

Maybe it is lens flare, though one thing going for it is the green is lower down and red is higher up, somewhat like often on Earth. Maybe all a coincidence though. It's also probably coming up too high off the surface to match with the scale of the image.

Bright plume BTW in image JNCE_2024165_62C00102_V01, just beyond the terminator on the limb, is Seth Patera, or well, the large flow field to its northeast.

No such lens glare or aurora spotted up north:

This just looks like stray light to me; note the curves in the red channel that look like reflections of the bright limb. We take these images because there's nothing else to do given the current image geometry, and while we call them "aurora search" it's not with much expectation that Junocam could see an aurora if there was one.

However, on Earth, those colors are due to oxygen and nitrogen, so it's unlikely that we'd see the same colors on Jupiter, except by coincidence. And with only three color bands, the range of possible permutations is pretty slim.
