JHelioviewer has been developed as part of the ESA/NASA Helioviewer Project. Users of JHelioviewer can zoom in on regions of the Sun that they wish to examine in detail. The tool allows users to overlay series of images from the Sun, from different instruments, and compile an animated sequence, which they can then manipulate as they watch, in order to follow a solar event from start to finish.This screenshot shows a view of the Sun, taken with NASA's Solar Dynamics Observatory (SDO) on 6 December 2010. JHelioviewer is an interactive, open-source software package that allows users to access over 14 years worth of data from the ESA/NASA Solar and Heliospheric Observatory (SOHO) along with the latest information beaming back from NASA's Solar Dynamics Observatory (SDO). This screenshot captures a view of the JHelioviewer user interface. In effect, it is a virtual observatory, says Müller.JHelioviewer screenshot (Filament eruption, NASA SDO) With JHelioviewer, users can visualise the Sun for any time period between September 1991 and today they can perform basic image processing in real time, track features on the Sun, and interactively overlay magnetic field. The goal of JHelioviewer, and the Helioviewer Project as a whole, is to offer intuitive interfaces to large datasets from many different sources. The JHelioviewer software is open source, platform independent, and extendable via a plug-in architecture. It also allows data to be annotated, say, solar flares of a particular magnitude to be marked or diseased tissues in medical images to be highlighted. This movie, constructed using ESA's JHelioviewer, captures not only the solar storms but the planet Mercury, as it orbits the Sun. A series of extraordinary eruptions exploded from the Sun during Halloween 2003. This is because JHelioviewer does not need to download entire datasets, which can often be huge it can just choose enough data to stream smoothly over the Internet. The code can even be reused for other purposes it is already being used for Mars data and in medical research. It is open-source software, meaning that all its components are freely available so others can help to improve the program. JHelioviewer is written in the Java programming language, hence the J at the beginning of its name. This is an interactive visual archive of the entire SOHO mission. With JHelioviewer, everyone can do this in minutes. ∻efore, it took hours to combine images from different telecopes to make a movie of the Sun for a given period. We wanted to make it easy to view solar images from different observatories and instruments, and to make it easy to make movies, says Daniel Müller, ESA SOHO Deputy Project Scientist. The data was captured by NASA's Solar Dynamic Observatory and the movie was constructed using ESA's JHelioviewer. JHelioviewer is being developed by the European. A gigantic mega-filament of incandescent gas erupts from the Sun. This video tutorial shows you how to use JHelioviewer, a new open-source visualization software for the Sun. They can export their finished movies in various formats, and track features on the Sun by compensating for solar rotation. Using this new software, users can create their own movies of the Sun, colour the images as they wish, and image-process the movies in real time. The downloadable JHelioviewer is complemented by the website, a web-based image browser. More than a million images from SOHO can already be accessed, and new images from NASAs Solar Dynamics Observatory are being added every day. Developed as part of the ESA/NASA Helioviewer Project, it provides a desktop program that enables users to call up images of the Sun from the past 15 years. JHelioviewer is new visualisation software that enables everyone to explore the Sun.
