Helioviewer.org 3.1 released

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.

Most recent LASCO and STEREO images temporarily unavailable.

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.

In the mean time, users can find near real time LASCO images at the SOHO homepage and the most recent STEREO images at the STEREO mission page.

One week from today: Transit of Mercury, May 9 2016

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:

Never look at the uneclipsed Sun with unprotected eyes!
Always use sun-safe optics to look at the Sun.
stripe_test_mercury_transit_01

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!

A New Generation of JHelioviewer Now Available

The Helioviewer Project is pleased to announce that a new generation of JHelioviewer is available for download from http://jhelioviewer.org and http://sidc.be/jhelioviewer.

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 .

Helioviewer.org 3.0 released

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 contact@helioviewer.org, and thank you for using the Helioviewer Project.

Direct Helioviewer.org to YouTube Video Uploading Now Available

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.

Beta release helioviewer.org 3.0 now available for testing

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

data icon

icon you will get a dialog that looks something like this:

data2

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!

Recent images available again at Helioviewer.org.

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.

Impact of YouTube’s new authentication protocol

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.
