Earth as seen from Akatsuki's UV camera
The photos were taken at around 20:50 on May 21 (I think that is Japan time, so it would be 11:50 UT if that were true). At the time, Akatsuki was about 250,000 kilometers from Earth, which subtended about 3 degres of its field of view.
Here are views from the other two instruments.
