You may need to restrict the range further. I'm seeing 404 errors across multiple bands for the timestamp "0240".

Thanks for the heads up! This is by design -- the call to `.filter()` here removes all 404'd images, so the animation still runs smoothly. There does seem to be sporadic gaps in the data, but it's not clear why.

I see. They have indices of all their files at https://www.data.jma.go.jp/mscweb/data/himawari/index.html, but naturally those are don't allow CORS access. Neither does the data at https://himawari8.nict.go.jp/ unfortunately.
