Uranus System Imaging Options

[machi]

I finished my first good image of Uranus.
Planet is colorized from three filtered images (orange, green, blue).
Slightly brownish color of rings is entirely artificial.

I'd always assumed that was exactly the working hypothesis. The planet's atmosphere is drastically different in appearance than it was during the V2 flyby, and the obvious major external change has been the angle of solar illumination.

The equatorial regions would generally be expected to have more dynamic activity than the poles. Sheer speculation, but I wonder if the addition of direct solar heating to them either increases atmospheric mixing or facilitates some sort of photochemical process, either or both of which act to clear the haze.

Oh yes, I am certain that you're right about that.
I posted when the thought struck me, though it quite obvious so I am certain it must have been mentioned somewhere.
