Context Service

The Context Service (CXS) creates images on-the-fly using a processing capability based on the IVOA's Universal Worker Service (UWS) Pattern. The CXS is used to generate different types of plots that are used by the HELIO Front End (HFE) to assist the user.

To use the CXS, make the required selections (the time range of interest, type of plot required, etc.) and then press "Send Request". The resulting image or movie should appear on the new page after a few seconds.

Currently the Context Service is able to create:

  • Plot of GOES light-curve for a selected time interval (soft X-ray or protons)
  • Plot of solar image for a selected date, over-plotted with the location of SXR flares
  • Plot the Parker Spiral for a selected date with the location of planets and spacecraft shown
  • Movie of an active region (NAR) using images from the SolarMonitor site   

The Context Service also provides enhanced access to:

  • Movie of coronagraph, etc. images for a selected time interval from the CDAW archive at NASA/GSFC

Recent Updates:

  • The Parker Spiral plot now creates links to Web sites with solar observations for the selected date
  • NAR Movie capability added on 10 July 2014
  • Flare location image now has links for the ARs into corresponding SolarMonitor inages
