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

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
