Set the latest image from Himawari 8 as your desktop background.

npm build downloads


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

himawari-bg is a command line program that lets you set the latest image from the Himawari 8 geostationary satellite as your desktop background.


Warning: requires magick

If you have homebrew installed, you can use that to quickly install imagemagick and graphicsmagick.

brew install imagemagick
brew install graphicsmagick

Once you have magick on your side, you can run himawari-bg anytime:

npx himawari-bg


Command Line

You can run himawari-bg on the command line with npx or via global install (npm i -g himawari-bg).

If you run himawari-bg with no arguments, it will download the latest image from Himawari-8 and set it as your desktop background.

👉 You have to set the background color of your desktop to black manually if you want it to look as cool as possible.

There are some options available if you'd like to go further:

Usage: himawari-bg [options]

    --outfile, -o         Location to save image. (default: ~/Pictures/himawari-images/$TIMESTAMP.jpg)
    --zoom, -z            The zoom level of the image. Can be 1-5. (default: 2)
    --date, -d            Time of the picture desired. Can also be "latest". (default: "latest")
    --infrared, -i        Capture picture on the infrared spectrum. (default: false)
    --parallel, -p        Parallelize downloads for increased speeds (can be CPU intensive). (default: true)
    --screen, -s          Screen to set the wallpaper on (macOS only). Options: "all", "main", screen index. (default: "main")
    --scale               Scaling method (macOS only). Options: "auto", "fill", "fit", "stretch", "center". (default: "fit")
    --version, -v         Show version information.
    --help, -h            Show help.


himawari-bg can also be used programmatically as a node module:

npm install himawari-bg

Here is an example of how it works in node:

const himawariBG = require('himawari-bg')

   * The location to save the resulting image.
   * Default: `~/Pictures/himawari-images/${Date.now()}.jpg`
   * @type {String}
  outfile: '/path/to/output/earth.jpg',

   * The time of the picture desired. If you want to get the latest image, use 'latest'.
   * Default: 'latest'
   * @type {String|Date}
  date: 'latest', // Or new Date() or a date string

   * The zoom level of the image. Can be 1-5 (default: 2)
   * Each zoom level requires more images to be downloaded and therefore stitched
   * together. Higher zoom yields a higher resolution image.
   * Default: 2
   * @type {Number}
  zoom: 2,

   * If set to true, an image on the infrared light spectrum will be generated
   * Default: false
   * @type {Boolean}
  infrared: false,

   * Screen to set the wallpaper on (macOS only)
   * Options: 'all', 'main', screen index
   * Default: 'main'
   * @type {String|Number}
  screen: 'main',

   * Scaling method (macOS only)
   * Options: 'auto', 'fill', 'fit', 'stretch', 'center'
   * Default: 'fit'
   * @type {String|Number}
  scale: 'fit'

All config settings are optional and have default values.

himawariBG returns a promise, so it can be used in an async workflow if needed.

const himawariBG = require('himawari-bg')

async function () {
  try {
    await himawariBG()
  } catch (err) {


Thanks to celoyd for the inspiring glittering.blue and jakiestfu for creating himawari.js.


It turns out himawari.js was inspired by this gist by MichaelPote which basically does the exact same thing as himawari-bg except in a Windows Powershell environment. So I unwittingly made something inspired by something that was inspired by something that does what I did. Internet! ¯\_(ツ)_/¯
