New Capabilities in Helioviewer Project Clients

Helioviewer.org enables the simultaneous exploration of multiple heterogeneous solar data sets. In the latest iteration of this open-source web application, Yohkoh SXT joins SDO, SOHO, STEREO, and PROBA2 as a supported data set. A newly enhanced user-interface expands the utility of Helioviewer.org by adding annotations to the imagery. Backed by data from the Heliospheric Events Knowledgebase (HEK), Helioviewer.org can now overlay solar feature and event data (selectively by type and detection method) through the display of interactive marker pins, region outlines, data labels, and information panels. The addition of a size-of-the-Earth indicator provides a sense of the scale to solar and heliospheric features for education and public outreach purposes.
