Normal Helioviewer services now resumed

Full Helioviewer Project services originating at NASA – helioviewer.org, JHelioviewer and the Helioviewer API – are now back up and running. Over the next couple of days we will be backfilling in missing data from the period October 1 – 17, 2013. Thanks to our colleagues at the Space Influences Data Center (SIDC) at the Royal Observatory of Belgium for providing Helioviewer services in that period.

JHelioviewer users who edited their user profile files to use the ROB server can switch back to using Helioviewer services at NASA by removing the edits

We thank you for your patience over the past couple of weeks.

Helioviewer Server Technical Difficulties

We are currently experiencing some technical difficulties with our main Helioviewer server. While we work on fixing it, we have moved all helioviewer.org services over to our backup server. All normal helioviewer.org services should be operating nominally. Please contact us if you notice anything amiss with helioviewer.org. JHelioviewer services are currently not operational, but we hope to have these up and running as soon as possible. Near real-time AIA and HMI images should be available as usual; streams of images from SOHO, STEREO and PROBA2 should be back to near real-time within 24 hours.

We apologize for the interruption to Helioviewer services, and we thank you for your patience.

Coding Opportunities for Students: JHelioviewer and SunPy join ESA’s Summer of Code in Space

ESA Summer of Code in Space 2012 (SOCIS) is a program run by the European Space Agency. It offers student developers stipends to write code for various space-related open source software projects. Through SOCIS, students will be paired with mentors from participating project teams, thus gaining exposure to real-world software development. The program is inspired by (but not affiliated or related in any way to) Google’s Summer of Code initiative.

JHelioviewer, in collaboration with the start-up company Luxunda, and SunPy have been selected as mentoring organizations, and students are encouraged to apply until 27 July 2012 (11 am UTC).

Helioviewer discussion forum is now online!

Alongside of our coverage of the last Transit of Venus that most of us will get to see (the next one will be in 2117 for those of you who are particularly ambitious!) we are also launching a new online discussion forum: community.helioviewer.org.

Screenshot of community.helioviewer.org

Here, users can share interesting features and events they find and get help identifying solar phenomena. In addition to forums on topics such as “transits and eclipses” to “coronal mass ejections,” we also have other sections including “solar physics” and “heliophysics” for anyone interested in learning more about the science that goes on behind the pretty pictures and movies.

 

Check it out and let us know what you think!

JHelioviewer 2.2.1 Released

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

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

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

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.
