Total Lunar Eclipse on September 16th, 1997
Total Lunar Eclipse occured on 1997 Sept.16. But, unhappily, almost japanese could not watch it because the 19th typhoon was hitting our country. We went to Miura peninsula (in Kanagawa pref., south of Tokyo), but we could not observe this event.
Following images were taken by Masakuni Yamazaki. He is a member of our sub group in Fukuoka. He observed at Yame city (in Fukuoka pref.) after the typhoon passed.
