Helioviewer Project services (helioviewer.org, api.helioviewer.org and JHelioviewer connections at NASA Goddard Spaceflight Center) will be suspended temporarily later today (6 March 2017) for necessary maintenance. The outage is anticipated to start around 4pm Eastern Standard Time. We anticipate that services will be suspended for about 24 hours. Normal service will resume as soon as possible. We apologize for any inconvenience this may cause.
The transition to using the HTTPS protocol broke Helioviewer’s YouTube sharing capability. We tracked down the source of the bug and have fixed it. YouTube sharing has now been re-enabled. Please let us know if you continue to encounter any problems sharing videos from Helioviewer.org to YouTube.
We apologize for any inconvenience caused, and thank you for using the Helioviewer Project.
The Helioviewer Project is pleased to announce that Helioviewer.org 3.1 is now available. This new version of helioviewer.org adds two new features, an event timeline and improved YouTube movie browsing.
The event timeline allows you to pan backwards and forwards in time, and zoom in and out, browsing what happened and when it happened on the Sun. It is accessible via a tab at the bottom of the viewer window, and works in the same way as the image timeline.
The YouTube movie browser now allows you to see if any shared movies include the date and time you are looking at. It’s a way of finding out what other people have seen on the Sun.
This new feature was suggested by a user of helioviewer.org. If you have a suggestion of how to improve helioviewer.org, please email us at firstname.lastname@example.org.
Thanks, and we hope that you enjoy this new version of helioviewer.org.
The computer that converts most recently acquired LASCO and STEREO observations to images served via the Helioviewer Project suffered a hardware failure on June 6 2016. This means that LASCO and STEREO images from June 6 2016 onwards are currently not available via the Helioviewer Project clients such as helioviewer.org and JHelioviewer. We apologize for the temporary unavailability of these images and any inconvenience it may cause. We hope to have the pipeline that supplies the most recent images up and running again in the next couple of weeks. Images before June 6 2016 are available as normal.
Mercury will transit the disk of the Sun on May 9 from 11:20 to 18:45 UTC. This is a rare event, and it will be observed by the Solar Dynamics Observatory. The last transit observable from the Earth was on November 8, 2006 and the next one won’t be visible until November 11 2019. Remember:
Always use sun-safe optics to look at the Sun.
The row of black dots indicate where Mercury will pass. SDO will be making special observations of the transit, and will be providing near-real time updates of images as they come. These observations allow SDO scientists to better understand how the Sun is oriented on SDO’s cameras.
Helioviewer will also be providing the images SDO. Check back on May 9 2016 to watch Mercury transit the Sun!
JHelioviewer is an open-source application for visualization of solar images based on the JPEG 2000 standard. It is part of the ESA/NASA Helioviewer Project and another client to the Helioviewer web services alongside the Helioviewer.org web application. Since 2013, the whole software stack was revisited under ESA Contract No. 4000107325/12/NL/AK, commonly referred to as “Space Weather HelioViewer”. Many of the new additions will be of particular interest to the Space Weather community.
The new JHelioviewer “2.10” is significantly faster and more robust while offering a large number of new features, e.g.:
- Access to new datasets (GONG, SOLIS, etc.) from 3 different servers (GSFC, ROB, IAS)
- Combined view from different vantage points (e.g. STEREO and SDO) for full sphere mapping
- Image projections such as orthographic, latitudinal and polar
- Yet more viewing options, such as running and base differences, and a side-by-side (multi-view) mode
- Timeline datasets viewing, synchronized with the time of the current image
- Integration of features and events from the Heliophysics Events Knowledgebase (HEK), and alerts from the COMESEP system.
- Magnetic field line extrapolations
A full description of the installation, running of the software and new features can be found in the online user manual.
The work was carried out by SIDC @ Royal Observatory of Belgium (ROB). The new JHelioviewer will continue to undergo improvements in the future, meanwhile feedback is welcome at swhv – at – sidc.be .
The Helioviewer Project is pleased to announce that Helioviewer.org 3.0 is now available. Try the quick interactive tutorial under the new Help (“?”) button for a quick introduction to the new Helioviewer.org.
Helioviewer.org 3.0 is a major redesign of the interface. The reason for the change was the desire to provide new capabilities to our users including:
– Image Timeline: quickly scan forward and back in time to find out which images are available when.
– Connect to science data providers such as the Virtual Solar Observatory and the Solar Dynamics Observatory Data Cutout Service.
– Automatically generate Solarsoft/IDL data download scripts from movie requests.
Please check out the updated user guide to find out more about Helioviewer.org 3.0. We have plans to make more and different data types available, and to add new features in the next few months.
Please send any comments and bug reports to email@example.com, and thank you for using the Helioviewer Project.
We are pleased to announce that it is once again possible to upload movies directly from helioviewer.org to your YouTube account. This feature should work just as it did earlier on this year. If you choose to share your movie with other users of helioviewer.org, a clickable image link to your movie will appear on the right hand side of the helioviewer.org application.
We apologize for the delay in returning this functionality to helioviewer.org. If you have any problems using this function of helioviewer.org, please let us know.
We are pleased to announce the availability of a beta release of helioviewer.org version 3.0. The beta release can be found at http://beta3.helioviewer.org. We are looking for bug reports, suggestions and comments on version 3.
This new version paves the way for many new features we are planning for the next year. The first new feature connects the images you see in Helioviewer to the science data. If you click the
icon you will get a dialog that looks something like this:
This panel connects the images you see to our partner data services, the Virtual Solar Observatory and the SDO cutout service. You can also download an automatically generated SunPy/Python or Solarsoft/IDL script; running the script will allow you to download the requested data.
A couple of things to note about this beta release:
(1) Recent images will NOT be available through http://beta3.helioviewer.org.
(2) YouTube movie uploading and Bitly link shortening are not available.
(3) Bug reports and suggestions for improvements are welcome!
We are pleased to announce that recent images are once again available at helioviewer.org. Data gaps from throughout the year are being filled in.
Two features are as yet unavailable – direct Helioviewer to YouTube uploading, and Bitly URL shortening functionality. All other functions should work as before. Users can make and download movies and post them to YouTube. We are working to get these features back as soon as possible.
Our thanks also go to our colleagues at the Institut d’Astrophysique Spatiale for their support and services whilst helioviewer.org was undergoing maintenance.
Colleagues at the Institut d’Astrophysique Spatiale in France have graciously stepped in to provide Helioviewer services while Helioviewer Project servers are undergoing maintenance.
To use the web client, please go to http://helioviewer.ias.u-psud.fr/helioviewer/. Note that the “Upload Video to YouTube” function is not available from this site.
Users of JHelioviewer can access Helioviewer Project services at Institut d’Astrophysique Spatiale by going to a href=”http://www.jhelioviewer.org>www.jhelioviewer.org and installing the latest version.
We thank the Institut d’Astrophysique Spatiale for volunteering their services while Helioviewer Project servers are undergoing maintenance.
We continue to experience issues in serving new images. The problem is still being diagnosed. We apologize for the interruption to the normal operation of Helioviewer Project services.

In the past week, YouTube changed their authentication protocol. The authentication protocol is used by helioviewer.org to allow users to upload movies directly from helioviewer.org to a user’s YouTube account. We are currently working on changing helioviewer.org to take account of the change in Youtube’s authorization protocol. Currently, it is not possible to upload movies directly from helioviewer.org to YouTube.
However, it is still possible to upload movies made by helioviewer.org. If you download the movie to your computer, log in to your YouTube account, and use that to upload and publish your helioviewer.org movie.
We apologize for the interruption in helioviewer.org’s ability to upload movies directly to YouTube. We are working on updating helioviewer.org to accommodate the new YouTube protocol.
We are currently experiencing some performance issues with Helioviewer Project clients, helioviewer.org and JHelioviewer. We are working to diagnose the problem and to get our services back to nominal operations as soon as possible. We apologize for any inconvenience this may cause.
