Stationed in a halo orbit around the Earth-Sun Lagrange point since 1996, the Solar and Heliospheric Observatory (SOHO) has monitored the Sun for nearly 20 years. The Large Angle and Spectrometric Coronagraph (LASCO) instrument blocks out the bright solar disk, making it easier to see the corona of plasma and dust around the Sun, normally only visible during solar eclipses. This instrument also provides a very large field of view of the region around the Sun.
In addition to the benefit of this capability in solar studies, SOHO/LASCO can see many comets which pass very close to the Sun, called 'sungrazers'. Observers on Earth rarely see these objects as they are obstructed by the Sun's glare and Earth's atmospheric scattering at sunrise and sunset. SOHO/LASCO has seen not only many known comets, but discovered many more NEW sungrazing comets. At the time of this writing, the discovery count is approaching 3000.
There are nearly sixteen comets and trajectories plotted in these visualizations which covers the time frame from January 2005 to December 2013 at the rate of one frame of the movie corresponding to one day.
The trails are color coded based on group membership.

Yellow - non-periodic comets Cyan - Periodic comets
Important Notes and Caveats:
- The trails represent the orbital path of the comet nucleus, NOT the meant to represent the comet tail.
- This visualization was actually a small 'test of concept' for the larger visuals, 'Lots of Comets', linked below.
