Spectroscopic and infrared observations of Comet Sugano-Saigusa-Fujikawa (1983V) were obtained during its close approach to the Earth on 11-14 June 1983. The [O I] production rates of 1.8 +/- 0.9 x 10(26) atoms/s observed on 12.3 June and 7 +/- 3.5 x 10(26) atoms/s on 13.4 June lead to derived water-production rates of 3 x 10(27) mol/s on 12 June and 1.1 x 10(28) mol/s on 13 June. The abundances of the minor species NH2, CN, C2, and C3 are unusually low relative to [O I]. The upper limit to the average nuclear radius from our infrared and visual photometry on 12-13 June (assuming that the entire signal came from the nucleus) is approximately 370 m. The dust/gas mass ratio was <0.01 on June 12 and <0.005 on June 13.

Comet Sugano-Saigusa-Fujikawa (1983V) - 一颗小而令人费解的彗星

Sugano-Saigusa-Fujikawa (1983V) 彗星在 1983 年 6 月 11 日至 14 日接近地球期间获得了光谱和红外观测结果。 [OI] 生产率为 1.8 +/- 0.9 x 10(26) 原子/秒6 月 12.3 日和 7 +/- 3.5 x 10(26) 原子/秒 6 月 13.4 日观察到的结果导致 6 月 12 日和 1.1 x 10(28) mol/s 的衍生产水速率为 3 x 10(27) mol/s s 在 6 月 13 日。次要物种 NH2、CN、C2 和 C3 的丰度相对于 [OI] 异常低。我们在 6 月 12 日至 13 日（假设整个信号来自原子核）的红外和视觉光度测量的平均核半径上限约为 370 m。6 月 12 日的粉尘/气体质量比 <0.01，6 月 13 日的<0.005。
