Abstract
Comet C/1999 S4 (LINEAR) showed a very special behaviour between 28 June and 1 July 2000. Optical observations of the dust coma in two distinct continuum bands revealed that it changed morphologically as well as in colour. The two-dimensional coma morphology indicates a splitting of the nucleus which probably occurred shortly before the observations of 28 June 2000. The distribution of the dust particles in sun and tail direction reflected by the slopes of the radial profiles indicate the presence of a considerable amount of disintegrating dust particles in the sunward hemisphere and an overabundance of dust, reflecting at 440 nm, within the first 18,000 km of the dust tail. The spatial profiles of the (BC—RC) colour index in sun direction are distinctly different on 28 June and 1 July, indicating the production of a large amount of particles observable in blue continuum after 28 June.
Based on observations at Wendelstein Observatory.
