Overlaying data from three SOHO instruments in JHelioviewer to view solar events at multiple scales. It greatly speeds up the process," he added.
"JHelioviewer is a novel way of visually browsing the archive you can quickly identify interesting stuff and then go and get the scientific data. As part of a lengthy process you'd turn it into an animated sequence, that may or may not turn out to be useful," Daniel Müller, SOHO Deputy Project Scientist, explained. "If you wanted to study a phenomenon in a specific region on the Sun on a certain day then you needed to download a large volume of data and calibrate it with the appropriate software. The challenge is that with this vast and ever-growing forest of data it is hard to see the wood from the trees. This will be key in achieving SDO's goal of helping scientists understand how the Sun's magnetic field is generated and structured and how this stored magnetic energy is converted and released into the heliosphere. At 6000 times the data rate of SOHO, and containing a constant stream of high-resolution images of the Sun over 10 spectral channels, the volume of data from SDO has made it necessary to develop new ways of visualizing the data.
This solar opus is beginning to be complemented by SDO, which is returning 1.5TB of data per day. With 12 instruments on board, probing every area of our star - from its interior out to the corona and the solar wind - SOHO has compiled a vast library of solar data. Since then, the space telescope has delivered a daily stream of 250MB of solar data back to researchers on Earth. The Sun has been under almost constant human surveillance from space since the SOHO mission was launched in December 1995. Screenshot of the JHelioviewer user interface. JHelioviewer allows easy access to 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).
If request parameters `verbose` is set to `true` and `jpip` is omitted or set to `false`, the reponse is a JSON object containing an HTTP-protocol link to the JPX movie plus the timestamps of each frame a message if the value of `cadence` was overridden by the server.ESA offers a new way of looking at the SunĮSA has released interactive, open-source software that gives both scientists and the public an unprecedented insight into the ever-changing face of the Sun. If no cadence is specified, the server will attempt to select an optimal cadence. The desired amount of time (in seconds) between each frame in the movie. Optionally return a JPIP URI string instead of the binary data of the movie itself, or instead of an HTTP URI in the JSON response (if `verbose` is set to `true`). If set to `true,` the JSON response will include timestamps for each frame in the resulting movie and any warning messages associated with the request, in addition to the JPX movie file URI.
Currently, only JPX image series support this feature. Generate a `linked` JPX file containing image pointers instead of data for each individual frame in the series.
