See Earth from Himawari-8 on your desktop every 10 minutes.

Stability Version Build Status Code Style


"Himawari" (ひまわり) is Japanese for "sunflower". 🌻

Himawari 8 is a geostationary weather satellite deployed by the Japan Meteorological Agency. It takes photographs of Earth every 10 minutes.

hi8 is a macOS menubar app that sets the latest image from Himawari-8 as your desktop background every 10 minutes.

This project is alpha quality, please report any bugs! and maybe fix them! 😁


In the future, hi8 will be packaged as an app and downloadable via the releases page.

For now, you can install hi8 via npm.

npm install -g hi8


GraphicsMagick is an image processing library that helps stitch together the satellite images to produce a full picture of Earth.

The high resolution satellite images from Himawari-8 come in fragments like this one. At the resolution hi8 uses, there are sixteen images that need to be stitched together to create a full picture of Earth.

If you have homebrew, you can just brew install graphicsmagick.

If you know of a better (dependency-free) way to process the images (or package imagemagick and graphicsmagick with the application), please let me know!


Once hi8 and GraphicsMagick have been installed, all you need to do is run the hi8 command from a terminal.

hi8 will start in the background and from there it can be managed from the menubar.
