A new effort is underway to process the rapidly growing volume of solar observational data by using automated feature recognition and cataloguing software (c.f., Schrijver et al SPD 2007 or Hurlburt et al, SPD 2007). We apply a particular set of feature recognition tools called FINDSTUFF, available within the SolarSoft IDL framework, to the problem of automatically extracting X-Ray Bright Point (XBP) features from images recorded by the XRT instrument aboard the recently launched Japanese Hinode satellite. The extracted events are automatically catalogued by the FINDSTUFF software. The events are converted into standardized XML format as VOEvents, and these XML event files in turn are automatically deposited in the Heliophysics Knowledge Base (HKB) being developed at Lockheed Martin in collaboration with other institutions (c.f., Hurlburt et al, SPD 2007). In addition to providing a very useful end-to-end test of the Heliophysics Knowledge Base Project (Schrijver et al), the catalogue yields a valuable scientific database of XBPs extracted from high resolution XRT images. We discuss the aspects of our processing pipeline which are generally applicable to many feature archiving projects; we demonstrate how the final Heliophysics Knowledge Base may be queried to explore the XBP archive; we compare our catalogue of XBPs with previously generated ones; and we provide examples of discoveries made with massively autonomous feature extraction (MAFE).
The U.S. XRT team is supported by NASA contracts from NASA to SAO (XRT), while the SOT team is supported by NASA contract number NNM07AA01C. Hinode is an international project supported by JAXA, NASA, PPARC and ESA. We are grateful to the Hinode team for all their efforts in the design, development and operation of the mission.
