Here is a little after-hours fun for all Mars aficionados out there: What's the weather like on Hellas? When do clouds come and go?
Five VMC observations obtained early in February show that clouds that form in the morning disappear in the afternoon. The attached image composite shows the five individual observations at different Martian day times.
We are looking down onto the South Pole; the big bright albedo feature is the Hellas basin. Image processing here was minimal: The images were noise-reduced, saturation-enhanced, contrast-enhanced and eventually sharpened. They were then rotated to roughly fix Mars' orientation with respect to the image frame.
