Английская Википедия:August 1971 lunar eclipse
Шаблон:Short description Шаблон:Infobox lunar eclipse A total lunar eclipse took place on Friday, August 6, 1971, the second of two total lunar eclipses in 1971. A dramatic total eclipse lasting 1 hour, 39 minutes and 24.8 seconds plunged the full Moon into deep darkness, as it passed right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may have been stained a deep orange or red colour at maximum eclipse. This was a great spectacle for everyone who saw it. The partial eclipse lasted for 3 hours, 35 minutes and 31.9 seconds in total. Occurring only 2.2 days before perigee (Perigee on Monday, August 9, 1971), the Moon's apparent diameter was 3.6% larger than average and the moon passed through the center of the Earth's shadow.
Visibility
It was completely visible over Africa and Asia, rising over South America, and setting over Australia.
