Quote:The trick of lighting also explains its appearance in all wavelengths from near-IR to Blue.I could be wrong, so feel free to poke holes in my hypothesis.
Quote:Interesting, though I'm sticking with my simple explanation.
Quote:I suspect this is a rare trick of lighting, not a cloud. I measured the position of the feature in WinJUPOS, and (if I did the measurements correctly) it appears to correspond to the highlands that surround the large Martian craters Newton and Copernicus. Thus the area in question gets sunlight before the surrounding region at only this time of year. Additionally, its appearance is exaggerated due to sharpening; the area of our planetary images most distorted by sharpening is the limb.

"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
Quote:Hmm. The name John Mellish springs to mind...
Quote:I would just not go for the dust storm hypotesis. This feature's albedo (those features ?) is clearly more visible in short wavelenghts (blue/green) that in red/IR - just the contrary that what we should expect for dust.
