A penumbral lunar eclipse took place on August 6, 2009, the third of four lunar eclipses in 2009. The moon's small entry into the Earth's penumbral shadow will produce an extremely subtle dimming of the moon's southern edge, difficult to observe visually.

Visibility
The eclipse was completely visible over Africa and Europe and South America. It was seen rising over eastern North America and setting over Asia.
Lunar year cycles (354 days)
The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.
