UPDATE: new functionality for the Earth scale tool

In response to user feedback, the Earth scale tool (located in the bottom left hand corner of the viewer window) has some new functionality:

(1) The Earth scale tool can now be toggled on/off using the diagonal arrow in the top left corner. When toggled off, it looks like this:

earth scale down

and the viewer window looks like this

fullscreen with earth toggle off_red_box

You can see the Earth scale toggle in the bottom left hand corner highlighted by the red box. When the Earth scale in the “off” mode, it does not appear in any screenshots or movies, for example:


When the toggle is on, the Earth scale appears in your movies and screenshots:


Pressing the diagonal arrow in the Earth scale tool


at any time returns the Earth scale tool to the bottom left hand corner and sets it to “off” so it will not appear in any screenshots or movies.

(2) The Earth scale tool is now draggable to anywhere in the viewer window. This makes it easier to compare the size the Earth to solar and heliospheric events; for example,


Sunspots are pretty big, and that coronal hole is enormous, compared to the Earth.

We hope you enjoy this updated capability. We welcome your feedback regarding Helioviewer. If you have any other ideas about how Helioviewer can be improved, we’d love to hear them! Thanks!

    Thank you for this awesome tool and thank you for sharing all the data. It’s really appreciated as someone like me wouldn’t be able to see and play with this otherwise. Huge kudos to you guys!
    Keep up the great work!

      We are glad that you are enjoying Helioviewer and the latest images from our Sun and inner heliosphere.

    Great to have the Earth Scale Tool!
    It would, however, be much more aesthetically pleasing if the frame around the “Earth” did not show in the movies or sreenshots.
    Thanks to all at HV!

    I’m sorry if this question is stupid, but here goes anyway: How do you get the green pic on the Helioviewer?

    Will the Earth scale function tool also become available in jhelioviewer software or perhaps it’s already there but i just can’t find it ? ?

    Hi Michael,

    There is no Earth scale function in JHelioviewer – yet. We hope to have some more developments in the JHelioviewer software package in the upcoming year.

    Thanks for your suggestion!
