JHelioviewer 2.2.1 Released
Posted by Daniel Müller in AIA, Development, General, HMI, JHelioviewer, LASCO, Movies, Releases, Science, SDO, SOHO on April 10, 2012
A new version of JHelioviewer is available for download. What’s new? This update release contains improved movie export functionality, an updated LASCO C2 coronagraph mask, the new SDO Cutout Service plug-in plus various bug fixes.
The new movie export menu makes it easier to set the exact scaling of the area you are interested in, and the processing itself is now performed on the graphics card using OpenGL:
The SDO Cutout Service plug-in allows you to request science-quality image data from the SDO/AIA and HMI instruments for the region of interest and time range selected in JHelioviewer:
Service resumed
Posted by jack in AIA, General, Helioviewer.org, JHelioviewer, News, SDO on September 21, 2011
We are very pleased to announce that Helioviewer Project services are now back online.
This means that Helioviewer.org, JHelioviewer, and other applications that use Helioviewer Project services are now available and should be working as before. If you encounter any problems with any of our services please let us know. We are currently filling in missing data from 2011/08/05 through to 2011/09/16, and we ask for your patience during the next couple of weeks as we fill in the gaps. If you notice any gaps, please let us know, as we are eager to have as complete a record of solar activity as possible.
We do apologize for the interruption in service. This was caused by two distinct and unfortunately simultaneous hardware malfunctions on our server that took a long time to repair. We are looking exploring options that will ensure such a long break in service does not happen again. We are back now, and we hope you continue to explore your heliosphere!
JHelioviewer 2.1.4 is out
Posted by Daniel Müller in General, JHelioviewer on July 5, 2011
Due to the growing user community of JHelioviewer and helioviewer.org, our server traffic has increased significantly. This bug fix release, together with the deployment of our new open-source JPIP server addresses a number of bugs, some of which were related to high server load.
2011/06/27 – AIA data availability problems
Posted by jack in AIA, General, Helioviewer.org, JHelioviewer, News on June 27, 2011
We apologize for the lack of new images from AIA. This is due to issues outwith our control. We create the images you see from AIA level 1.5 data products (the number refers to the degree of image calibration, etc., that has been applied to the raw data) that are processed at SDO Joint Science Operations Center. As you can see, those data appear to be lagging at the moment. As soon as the data returns, Helioviewer will automatically generate images and make them available.

Dan Pendick recently posted an excellent series of articles about the Helioviewer Project on his blog, Geeked on Goddard. In five short articles Dan describes many of the different parts of the project, including Helioviewer.org and JHelioviewer. He also discusses some of the technologies that have made all of this possible. If you are interested in learning more about the project and how it all works, you should definitely check out the articles. Also, if you are a science/tech enthusiast I would highly recommend subscribing to Dan’s blog where you can learn more about some of the other cool projects that call the NASA Goddard Spaceflight Center their home.

JHelioviewer 2.1.3 is out
Posted by Daniel Müller in AIA, General, HMI, JHelioviewer, News, Releases, SDO, SOHO on February 25, 2011
The latest JHelioviewer update adds support for SDO/HMI data and features a new contrast filter, as well as an improved plugin to access the Heliophysics Event Knowledgebase (HEK).
AIA images are coming back
Posted by jack in AIA, Helioviewer.org, JHelioviewer, JP2Gen, SDO on January 3, 2011
You may have noticed that we didn’t have any new AIA images, from about 2010/12/19. This was due to an interruption in the creation of the science-quality files we use to create the images available via the Helioviewer Project. The situation has been rectified, and we are currently filling in missing data between now and when the interruption began (approximately 2010/12/19 04:00 UT). We are filling in the missing data at the approximate rate of 1.5 – 2 days worth of AIA images per 24 hours.
