HelioSoftware

Four tools that put the Sun where you already work: on your screen, in your file browser, at your research desk, and in your Python notebook.

For your screens

Heliogram

The live Sun as your desktop picture, your screen saver, or a wall of video. Imagery from NASA's Solar Dynamics Observatory.

macOS · direct download

For your Finder

HelioFITS

Solar FITS files rendered as the Sun, right in Finder and Quick Look: the instrument's colormap, real coordinates, and metadata you can search in Spotlight.

macOS · free on the Mac App Store

For your science

HelioFITS Studio

A compositor and work surface for scientists studying the Sun's outer corona, built for PUNCH, LASCO and other coronagraph data.

macOS now · Windows and Linux in testing

For your figures

RHEF

The Radial Histogram Equalizing Filter: one call that brings out faint coronal structure on the disk and off the limb, with no tuning.

Python · pip install sunkit-image

Which one do I want?

• You'd like to look up and see today's Sun: Heliogram.
• You have a folder full of .fits files and no idea which is which: HelioFITS.
• You're following a CME out through the coronagraphs: HelioFITS Studio.
• Your figure shows a bright ball in a dark void, and you know there's corona out there: RHEF.
• All four: they get along fine.

What's new: release notes and an Atom feed.

Shared contracts for these tools (checksums, rules for agents, drift checks) live in the spec folder.
