We discuss the properties of the nucleus and inner coma of Comet Hale–Bopp (C/1995 O1) as derived from observations of its occultation of Star PPM 200723 on 5 October 1996, while the comet was 2.83 AU from the Sun. Compared to previous occultations by active comets, this is possibly the closest to the nucleus one has ever observed. Three chords (lightcurves) through the comet’s inner coma were measured, though only one chord has a strong indication of measuring the occultation, and that was… CONTINUE READING
