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 |

This de-rotated animation shows the night side of Venus in IR.
Near the center you can see a giant, previously unknown planet-scale wave feature. The animation covers about 14 hours of observations ![]() -------------------- |

The animation covers about 14 hours of observations ![]() Beautiful work, Roman. I have photographed Venus in UV regularly and it's nice to see the cloud motion occur on this time scale. From Earth, one can see about 3 hours maximum in sequence, and then the change a day later, after which the planet has rotated 90°. Many of the details here are moving on a scale of minutes and it both beautiful and illuminating. I'm unsure what the planet-scale wave feature is: Is that dark curve across the middle the feature, or an artifact? Akatsuki found a gigantic planet-scale wave running north to south early in its mission, but the imagery didn't look much like this. Is this another example of that phenomenon? |

Current amateur UV studies of Venus are amazing. One correction: the rotation period of Venus is 243 days and the superrotation of the atmosphere is 96 hours, so that "day later" was a view of the atmosphere. -------------------- |
