Since JHelioviewer is still rapidly evolving, this document may not reflect entirely all the capabilities of the software. The events can be visualised on both the images and the timelines.
Both the Heliophysics Events Knowledgebase and the COMESEP project provide the events. Several types of space weather related events can be displayed. The time interval displayed can be translated and zoomed freely. The timeline viewer shows one-dimensional and two-dimensional data.
Field lines of the solar magnetic field calculated by a PFSS model can be displayed. Other projections are available, such as solar latitudinal or (log)polar. They can be rotated, translated, and zoomed in and out the sphere. The solar images can be projected on a sphere. The viewer is able to display solar image data, and one-dimensional and two-dimensional solar timeline data. The JHelioviewer solar data visualisation tool has been overhauled with a strong focus for space weather usage.

This project builds upon the infrastructure of ESA/NASA Helioviewer Project ( ) at all levels of the software stack, and significantly augments the capabilities of the JHelioviewer software ( ). 4000107325/12/NL/AK - High Performance Distributed Solar Imaging and Processing System - run at the Solar Influences Data Analysis Center (SIDC, ) of the Royal Observatory of Belgium (ROB) under the supervision of Space Environments and Effects section of ESA (ESTEC/TEC-EES, ). Space Weather JHelioviewer is an outcome of the ESA Contract No.

As a first step towards supporting science planning of the upcoming Solar Orbiter mission, JHelioviewer offers a virtual camera model that enables users to set the vantage point to the location of a spacecraft or celestial body at any given time.JHelioviewer User Manual JHelioviewer User Manual Once an interesting event has been identified, science quality data can be accessed for in-depth analysis. The software integrates solar event data and a timeline display. Results: 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 extrapolations.
The JHelioviewer software is open source, platform independent, and extendable via a plug-in architecture. Methods: The JPEG 2000 standard offers useful new features that facilitate the dissemination and analysis of high-resolution image data and offers a solution to the challenge of efficiently browsing petabyte-scale image archives. Since the first release of JHelioviewer in 2009, the scientific functionality of the software has been extended significantly, and the objective of this paper is to highlight these improvements. From a scientist's perspective this poses three problems: accessing, browsing, and finding interesting data as efficiently as possible.Īims: To address these challenges, we have developed JHelioviewer, a visualisation tool for solar data based on the JPEG 2000 compression standard and part of the open source ESA/NASA Helioviewer Project.

In particular, the large volume of SDO data presents challenges the data are available only from a few repositories, and full-disk, full-cadence data for reasonable durations of scientific interest are difficult to download, due to their size and the download rates available to most users. Solar and Heliospheric Observatory, SOHO), multiple viewpoints (Solar TErrestrial RElations Observatory, STEREO), and returning large amounts of data (Solar Dynamics Observatory, SDO). Solar observatories are providing the world-wide community with a wealth of data, covering wide time ranges (e.g.
