I cannot remember because there were some Yunan Observatory staff around.
There was also 1 non-member in our delegation : Yeung Kai Hing (楊繼興) of the HK Royal Observatory who undertook to measure changes of air temperature during the eclipse. His project was the only successful one because the Sun was behing a large "stationary" cloud during the totality. His result was published in the Observatory's Scientific Report in 1981.
The retire director of the Purple Mountain Observatory 張玉哲 was also there.
