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. A gigantic mega-filament of incandescent gas erupts from 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. This revelation increases the work load for space weather forecasters, but it also increases the potential accuracy of their forecasts.JHelioviewer is new visualisation software that enables everyone to explore the Sun. "To predict eruptions we can no longer focus on the magnetic fields of isolated active regions," says Title, "we have to know the surface magnetic field of practically the entire sun." Solar flares, tsunamis, coronal mass ejections-they can go off all at once, hundreds of thousands of miles apart, in a dizzyingly-complex concert of violence. Instead, solar activity is interconnected by magnetism over breathtaking distances. With several colleagues present to offer commentary, they outlined their findings at a press conference today at the American Geophysical Union meeting in San Francisco.Įxplosions on the sun are not localized or isolated events, they announced. "We see that solar storms can be global events, playing out on scales we scarcely imagined before."įor the past three months, Schrijver has been working with fellow Lockheed-Martin solar physicist Alan Title to understand what happened during the "Great Eruption." They had plenty of data: The event was recorded in unprecedented detail by NASA's Solar Dynamics Observatory and twin STEREO spacecraft. "The August 1st event really opened our eyes," says Karel Schrijver of Lockheed Martin’s Solar and Astrophysics Lab in Palo Alto, CA. It was so big, it may have shattered old ideas about solar activity. Astronomers knew they had witnessed something big. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. On August 1, 2010, an entire hemisphere of the sun erupted. White lines trace the sun's magnetic field. Obtained by the Solar Dynamics Observatory on August 1st. Locations of key events are labeled in this extreme ultraviolet image of the sun, 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.
