The immense volume of data generated by the suite of instruments on SDO requires new tools for efficient identifying and accessing data that is most relevant to research investigations. We have developed the Heliophysics Events Knowledgebase (HEK) to fill this need. The HEK system combines automated data mining using feature-detection methods and high-performance visualization systems for data markup. In addition, web services and clients are provided for searching the resulting metadata, reviewing results, and efficiently accessing the data. We review these components and present examples of their use with SDO data.

  1. SADCat: A Catalog of Supra-Arcade Downflow Events in Solar Flares

    astro-ph.SR 2026-07 accept novelty 6.0 of 10

    A catalog of 178 SAD-producing flares shows peak GOES flux, duration, CME speed and mass strongly control visible SADs while impulsivity and acceleration do not.

  2. Multi-Instrument Observations and Tracking of a Coronal Mass Ejection Front From Low to Middle Corona

    astro-ph.SR 2025-08 conditional novelty 6.0 of 10

    A single CME observed in sequence by AIA, K-Cor, and LASCO shows the same dome-shaped front in EUV and white light, identified as a pile-up compression region behind a not-yet-detached wave.
