Space Weather Helioviewer is an extension of the JHelioviewer client application (user manual) with space weather relevant capabilities within a streamlined user interface. SWHV will therefore enable space weather forecasters in getting quickly an overview of the current space weather situation. The SWHV system allows its end users to combine the visualisation of various solar datasets in new ways. The supported data is heterogeneous: it contains 1D data (timelines); 2D data (solar images and spectrograms); 3D data (multi‐spacecraft imaging, magnetic field lines modelling), solar event detections (e.g., HEK) and space weather alerts. The features newly introduced by the Space Weather Helioviewer project will be highlighted and can be tested.

SWHV is being developed with funding from ESA General Support Technology Programme (GSTP) (SWHV, ESTEC Contract No. 4000107325/12/NL/AK) in order to support activities as part of the ESA Space Situational Awareness (SSA) programme. Software developed will be freely available for use by the whole space weather community (as is presently the case for Helioviewer)
