So my first thought was (will this replace the doves by space labs). Which was an earlier story on HN. https://news.ycombinator.com/item?id=8158295

It won't because these are geostationary satellites (if I read the post correctly). So you'd need at least 3 of these to get a good image and that's not even considering some of the bigger issues with this. I also don't think the resolution is on par. But the images will be really cool to see.

Will there be a place where they can be downloaded? A live Planet Earth desktop wallpaper would be pretty great.

Check this out: http://www.jma.go.jp/en/gms/largec.html?area=6&element=1&tim...

edit: The largest image resolution seems to be 800x800 (well, 800x815, with the attribution footer). I wonder if the new satellite's imagery isn't part of this feed yet? I hope that's the case, because it would be incredibly cool to be get such high-res images.

Nice. Japan needs better weather data; too many hurricanes and too much coastal development. From geostationary orbit, the resolution has to be low, but it's always on.

The US has two geostationary weather satellites, which are usually parked roughly over Panama and Hawaii. Neither has good coverage of Japan. Korea's COMS satellite does, though. China has several, including one that's usually pointed roughly at Taiwan.[1] Right now, you can see the hurricane that's due east of Shanghai.

The resolution of the "full disk" (i.e. whole earth) natural color images appears to be 11000x11000 pixels every 10 minutes. I can't find any realtime access to these images though - could anyone else?

They do have a cloud service for disseminating the imagery, but only for "official use":

"Until Himawari-8 becomes operational, NMHSs wishing to release Himawari-8 data and products to the public are requested to consult with JMA beforehand."

Edit: Here is at least a tile-zoomer with some sort of realtime access to high-res imagery: http://himawari8.nict.go.jp/

I hope that they upload the images to some server that we can grab and make animations with. I can watch this all day.
