Comet C/2006 M4 (SWAN)

 

C/2006 M4

 

Field size is approximately 0.5° x 2°, north is up, east to the left.

This comet was discovered on images obtained using the SWAN camera aboard the Solar and Heliospheric Observatory (SOHO) spacecraft during the period of June 20 to July 5, 2007. B. G. Marsden published an orbit for the comet in September 2007 which revealed that the comet moved in a hyperbolic orbit, making it a one-time visitor to the solar system.

Comet SWAN M4 was predicted to reach a maximum magnitude of 8-9, making it an object visible in telescopes only, but it actually reached the surprising brightness of approx. 4.2 in late October for 2007, when it was visible to the naked eye. The long and bright ion tail made it an interesting comet, when compaired to the small and relatively faint coma.
