Resource Detailed View


  • Responsible Thematic Node: Small Bodies, Dust, and TNOs
  • Short Name: SWAN-comet
  • Brief description: Detection and monitoring of water production of active comets
  • URL: http://www.aerov.jussieu.fr/projet/SWAN/images/
  • Type: DATA/Observational
  • English Language: YES
  • Start date: 1996-01-28
  • Restricted access: NO
  • Comment on the access:
    Open access to near-real-time images, and calibrated Lyman alpha intensities in ASCII table form

  • Longer description:
    The Solar Wind Anisotropy instrument SWAN on board SOHO is monitoring the Lyman alpha radiation of the whole sky once in 24 hours. By subtracting background and constant light sources like stars, subsequent images reveal moving targets, most likely comets. There water orbit parameters and production rates can be derived from the data sets

  • Processing level:
    Calibrated

  • Status (static or active ?):
    active

  • Howto URL 1: http://www.aerov.jussieu.fr/projet/SWAN/
  • Explain how to use it:
    The summary image table gives access to daily full solar system UV images processed for:
    - Space weather forecast (radiation on the Sun's far side in spheric coordinates and as Carrington rotation maps)
    - Lyman-alpha background maps of the solar system (solar wind distribution)
    - Static background removed images to highlight comets
