This lunar eclipse grazes the southern edge of the Earth's penumbral shadow occurs at the ascending node of the moon's orbit, in the constellation of Sagittarius
A penumbral lunar eclipse took place on July 7, 2009, the second of four lunar eclipses in 2009. This eclipse entered only the southernmost tip of the penumbral shadow and thus was predicted to be very difficult to observe visually. This lunar eclipse was the predecessor of the solar eclipse of July 22, 2009.
It was predicted to be seen rising over Australia after dusk on July 7 and setting over western North and South America in the early predawn hours of July 7.
