JHelioviewer is an open source project and its source code can be accessed at. The minimal OpenGL version required is 3.3. The supported computer architecture are Intel/AMD 64-bit and, on macOS, Apple Silicon (ARM64). It contains native compiled libraries to speed up critical operations. The JHelioviewer software does advanced data processing and visualisation therefore it works best on a reasonably recent computer with decent CPU and OpenGL graphics power, and memory. Information and support requests can be sent to Installing and Running 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. JHelioviewer is part of the ESA/NASA Helioviewer Project.JHelioviewer User Manual JHelioviewer User Manual For further information about the project, contact Daniel Müller (Daniel.Mueller esa.int). JHelioviewer is being developed as open-source software by the ESA JHelioviewer Team.

These features minimize the data volume transmitted while maximizing its usability. The JPEG 2000 Interactive Protocol (JPIP) enables serving data in a highly compressed, quality-progressive, region-of-interest-based stream. JPEG 2000 offers many useful new features and has the potential to revolutionize the way high-resolution image data are disseminated and analyzed. JHelioviewer is visualization software for solar image data based on the JPEG 2000 compression standard. However, work on JHV version 2 continues. The project is in maintenance mode and issues are fixed on a best-effort basis. Downloads are still available from and functional. This repository contains the no longer actively developed version 3 of JHelioviewer.
