Abstract:
Improvements in our understanding of heliophysic phenomena requires tools for conducting surveys of data and metadata to discern trends, correlations, and causation. The Heliophysics Events Knowledgebase (HEK) provides a system for collecting and presenting heliophysical data based on the Virtual Observatory (VOEvent) format and other standards. The HEK incorporates entries from distributed ground and space based solar observatories and event descriptions generated by automated algorithms, detailed data analysis and citizen scientists (while storing contact information and links to websites and papers for attribution purposes). This makes it possible to carry out integrated studies that span the full range of heliophysics and these resources are available to any interested researcher.
The HEK is transitioning to an infrastructure model to ensure that the archive persists beyond the life of the missions that shaped its development. We present features of the HEK that support construction of detailed workflows to conduct research involving fusion of multiple data and event sources via search tools that compute spatial and temporal overlaps between entries. We also outline improvements and new features planned and in development for the coming years, which include better tools and outreach to receive submissions from many more event lists and instruments to the HEK as well as improved support for coordinated, multi-instrument campaigns. In particular, we discuss improvements in the HEK API, expansion to support off-axis and in-situ events and possible extensions to support geospace missions.
