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

Fascinating, its a 16-hour sequence.. I don't recall ever seeing cloud animations for venus, unless i missed it.
Chrome did a pretty good job of translating, so might come in handy.. here's a the current state with translation of that page:

Venus night side of the moving image by IR2 camera [Click for larger image] [GIF: 5.5MB] © ISAS / JAXA

The original image [Click for larger image] © ISAS / JAXA IR2 videos of Venus night plane by the camera video was based on 2016 March 29, the Venus night side image taken from a distance 360,000 km in IR2 wavelength 2.26μm. Four original image has been obtained in the 4-hour intervals from 16 hours 03 minutes (JST). During 4 hours, clouds has moved approximately 10 degrees by the super rotation, so as to fill therebetween and a smooth moving by rotating slightly the original image by calculation. From the video, to understand as deformation and prevalence of clouds take in hand, if reduced to 2 hours and 1 hour imaging interval in a future of steady observation, it is possible to obtain a video of more smooth, high-definition, Venus atmosphere understanding of is expected to proceed at once.

Many dayside light that covers the brightness is strong 1.735μm in the night side of the, is because that's near the day and night boundary has become Orange sexy. The difference subtle shades of the night side is considered to represent the differences in the size of the cloud particles.

It's a challenge to get coverage sufficient to animate the clouds on Venus: Usually, a view covers only about 90° on the day or night side (whichever is being used), and it takes about 4 days for rotation to occur, so a given parcel of cloud is only seen for part of a rotation. It would be difficult to track the same area without interruption for longer than 2 days.
