Description

Near Nucleus Phenomena.

Using a film camera attached to the 0.114m reflector, I followed the linear jets and shells of comet Hale–Bopp between February and May 1997. The study of the shells revealed that the speed at which they move away from the nucleus was not constant. A periodic variation of the shell expansion velocity may be a possible precessional effect on the axis of rotation of the comet's nucleus.

Taken on April, 1997. The first shell (the innermost one and close to the false nucleus), originated from a jet formation, and is seen as an Archimedean spiral and the speed of the ejecta from the comet nucleus is 1.6 km / sec.
