About the Cover


Comet Hale-Bopp on 20 August 1996 observed from the European Southern Observatory, Chile, during the monitoring campaign to study the evolution of its activity. The image was taken through an R-filter (wavelength 530 to 950 nanometers) (exposure time of 15 seconds), and the jet structures have been enhanced. North is at the top, and the field of view is 3.4 arc minutes. See the related papers beginning on page 1900 and the Perspective on page 1895. [Image: H. Boehnhardt, M. Küppers, H. Rauer, K.
