Keck 1 HIRES Observations of Tempel 1 at the Time of Impactformed initially during the impact. After the first 600 s the time dependence of the intensities of the emission spectra species appear to be consistent with the photochemical formation and destruction of parents and daughters. The spectral changes with time associated with the CH emission appear to

This could indicate that the system nucleus-coma of the comet acquired a certain instability, an instability which lasted several hours.

To accomplish this goal, background spectra due to ambient emission that was already present in the comet were extracted from the pixels at the end of the slit.

This paper discusses aspects of observational accuracy achieved by untrained observers using standard CCD cameras at 0.5 and 1-m class telescopes in South Africa and Chile. Our experience illustrates that calibrated photometry of comets cannot be accomplished without dedicated

Comets, Charisma, and Celebrity: Reflections on Their Deep ImpactThrough images, ranging from the sublime to the humorous, it probes the reasons why comets are among the most charismatic visual spectacles in the universe and why, even as scientific missions unmask their mysteries, they remain iconic symbols and harbingers of change.
