摘要：

Photographic photometry of (2060) Chiron was carried out using a set of archival plates taken between 1969 and 1977. The data reveal an extensive interval of brightening, presumably due to an increase in cometary activity, when Chiron was near aphelion. This activity substantially exceeded, in both magnitude and duration, the activity observed as Chiron approached perihelion near the end of the 1980s. (C) 2001 Academic Press.
