I thought it was time to start a separate thread on this mission, launching soon
some good medium-resolution images of the spacecraft are available on JAXA digital archives http://jda.jaxa.jp/jda/p3_e.php?time=N&...mp;mission=4066 |

I'm curious whether any of the recent data or images would show how much limb darkening Venus exhibits at a low phase angle (fully lit). Is it possible to assess this with an image using only visible wavelengths?

I'm curious whether any of the recent data or images would show how much limb darkening Venus exhibits at a low phase angle (fully lit). Is it possible to assess this with an image using only visible wavelengths? That's an issue that I would love to see addressed. It certainly seems in all images that I've seen that this has at least some difference, though subtle, across the visible spectrum. Venus Express imaged a glory on Venus, which implies that such a thing is perhaps in their data, unless the whole disk was not imaged. I haven't seen any such image that captures such a wide view. Over the last few months I've been extremely eager to get a terrestrial photo of Venus at its fullest. I captured an image just four days ago with Venus at a phase angle of 18.5°. (And immediately thereafter, an image of Mercury.) I wish it'd been less, and/or that the quality were higher, but weather has not been helping me out. I've seen few terrestrial images of a relatively "full" Venus in color. Perhaps what you are looking for can be approximated with this or a better terrestrial image. |
