What you're stuck on, and which tool gets you unstuck

Every need a solar scientist, student or Sun fan brings to the suite, in the order the work happens: find the data, look at it, work with it, make something, share it. Dashed cards are approved but not built yet. Cards with a grey edge are planned utilities that will fold into an existing product rather than ship on their own.

Available now Approved, not built Planned, folded into another product

Find it

The empty seat today. Heliad fills it.

I don't know how to get the data I need.
Heliadplanned

Search by time, instrument and wavelength; queue downloads from the archives and resume them when the connection drops.

My downloads are in five folders and half of them are duplicates.
Heliadplanned

One library with one folder convention, checksums verified on arrival, duplicates caught.

I want new frames to show up on my disk as they're released.
Heliadplanned

Watch a source or a folder; new files land in the library and get indexed.

Is this header lying to me?
Heliadheader checks folded inplanned

Headers and WCS are checked as files arrive: rotation keys that disagree, the wrong time scale, a solar radius that doesn't match the plate scale.

Which of my Sun tools are out of date?
Heliadplanned

A read-only status pane showing installed and latest versions from the family release feed. Each app still updates itself through its own channel.

Look at it

Seconds, on a file you already have.

I can't see which file is blurry.
HelioFITSavailable

Finder thumbnails render every FITS file as the Sun, in the instrument's colormap.

I have a folder full of .fits files and no idea which is which.
HelioFITSavailable

Press Space for a Quick Look preview with real coordinates; search the metadata in Spotlight.

I'm not on a Mac, or the file is on a cluster I just logged into.
HelioFITS Webplanned

Drop the file on a web page. It renders in your browser; nothing uploads and there's no account.

I want to see the image without leaving my editor or notebook.
HelioFITS for VS Code and Jupyterplanned

Inline previews where you already work.

I need headers and thumbnails from a script.
HelioFITS CLIplanned

Header dump, render and contact sheets from the command line, ready for a Makefile.

3

Work with it

Sit down with a series and follow the physics.

I'm following a CME out through the coronagraphs.

Layers, timelines and movies for coronagraph and wide-field data such as PUNCH, SOHO/LASCO and PROBA-3/ASPIICS.

What changed between these two frames, or these two instruments?
HelioFITS StudioandHeliadcompare folded inplanned

Studio aligns and differences layers across instruments. Heliad blinks two files in your library side by side.

My figure shows a bright ball in a dark void, and I know there's corona out there.
RHEFavailable

One call in sunkit-image brings out faint structure on the disk and off the limb, with no tuning. A visualization, not a calibrated radiance.

4

Make something

From a good look to a figure you can submit.

I need a journal-ready panel, and I'm tired of rewriting the same matplotlib code.
Studio,HelioFITSandHeliadfigure export folded inplanned

WCS axes, a colorbar with honest limits, limb and scale bar, sized to a journal column. One panel from Studio or Quick Look; a batch of panels from a Heliad selection.

Share the Sun

Imagery to look at, show off and hang up.

I just want to look up and see today's Sun.
Heliogramavailable

The last 48 hours of the Sun as your desktop picture, screen saver or a wall of video. macOS.

I want to check on the Sun from any browser, with nothing to install.

Near-real-time SDO/AIA views on a web page, updated every 20 minutes, with a 48-hour timelapse for every channel.

Our lobby has a TV, not a Mac.
Heliogram for Apple TVplanned

The same clips on a living-room or lobby screen.

I want the Sun on my phone.
Heliogram on iPhoneplanned

Today's Sun as a widget and on the lock screen.

I want the live Sun on our department's website.
Live Sun embedplanned

Paste one snippet and the 48-hour Sun plays on your page, with credit and a link back.

I want a print of the Sun from the day I was born.
My Heliographavailable
