他为了比较欧洲和东亚在金星凌日期间,同时观测金星和太阳的米粒组织而产生的视差。要求职拍摄时间为UTC 8:00UT, 8:30UT, 10:00UT,相距最多不超过20秒,有这样照片的同好请直接寄给他,谢谢。下面为邮件原文。
WNM注:同时拍到金星及米粒组织的高分辨率照片才能符合要求。

Dear Wang Ning Min,

During the venustransit we had
acceptable conditions in Germany.
So it was possible to produce
some fine pictures from venus and the solar granulation.
It would be intersting to compare the european
results with pictures form east-asia.
A parallax in front of the granulation should
be visible !!
I have pictures from 8:00UT, 8:30UT, 10:00UT
and 10:30 UT. Now I´m searching for asian counterparts.
The pictures should have a similar time because
the planet changes the position one arcsecond
in every 16 time-seconds. But +-20 sec are acceptable.
May you can help me to find some pictures.
Would you like to publish this mail
in some asian astro-mail-groups?

Regards
