Comet 17P/Holmes Development in November
This set of images shows the development of Comet 17P/Holmes
over a few weeks in November 2007. While the nature of
the film media and digital post-processing preclude serious
measurements, the expansion of the
central dust coma, weakening of the fluorescent gas shell,
and disconnection and disappearance of the blue ion tail
are apparent.
