| Abstract: | During our monitoring observations of comet Hale-Bopp, we found several sporadic ejections of dust from the nucleus. The most
prominent ejection was observed on May 6–9, 1997, in the post-perihelion phase of the apparition. In this paper, we report
preliminary analysis of this event, in which the total mass of the dust cloud is estimated to be 1.6 × 1011 g.
