摘要：利用1969年至1977年间拍摄的一组档案底片，对（2060）凯龙星进行了光度测定。数据显示，当凯龙星接近远日点时，可能是由于彗星活动的增加，有一段很长的增亮间隔。这种活动在规模和持续时间上都大大超过了20世纪80年代末凯龙星接近近日点时观测到的活动。
Abstract 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.
