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.
We have added more options when creating a movie. After you have selected the data and area you want you’ll see the new “Advanced Settings” option in the bottom left hand corner of the movie settings dialog:
If you click on that the dialog will be replaced with the one below. You can now specify the exact start and end times of your movie.
The size drop-down menu allows you to specify the size of the video you want – HD, Full HD, Quad HD or 4K/Ultra HD.
Helioviewer will automatically resize the movie to give you the best resolution video available at the size of the video you request. Helioviewer will remember if you are using the advanced or regular movie settings for making movies.
If you would like any other movie formats included, or if you encounter any problems using this new functionality, please let us know. Thanks for using the Helioviewer Project!
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.
Helioviewer.org is moving to using HTTPS instead of HTTP. This means that all communications between your browser and helioviewer.org are encrypted. The switch to using HTTPS only will happen on September 30th. An unfortunate side effect of this is that your helioviewer.org movie and screenshot histories will be lost. This is due to security features in your browser, which are explained below.
Helioviewer.org uses the HTML5 LocalStorage property to store your links to the movies on your computer. LocalStorage does not allow data from a regular HTTP page (for example http://htmlui.com) to be accessed by pages served from its HTTPS version (for example, https://htmlui.com, and vice versa. This is done to improve security; for example, you want to isolate values created during a secure session from unsecured sessions. The practical effect of this security is that when we switch to using HTTPS, the histories created when helioviewer.org was using HTTP cannot be accessed by your web browser when helioviewer.org starts to use HTTPS. So your movie and screenshot histories will not be viewable in helioviewer.org.
The switch to using HTTPS does not affect any movie links to helioviewer.org. If you have a link for example, http://helioviewer.org/?movieId=KSJd5 , then the server will automatically switch to using the secure version, https://helioviewer.org/?movieId=KSJd5 . Please make a note of any movie links you want to keep a hold of.
We apologize for any inconvenience this may cause. If you have questions concerning the change from HTTP to HTTPS, please let us know.
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 email@example.com.
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 firstname.lastname@example.org, 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.
