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.[1] 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.

Lunar year (354 days)Edit

This eclipse is one of five lunar eclipses in a short-lived series. 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.

Saros seriesEdit

This eclipse is a member of Saros series 110. The previous event occurred on June 27, 1991. The next event is on July 18, 2027 which will end the series.

Half-Saros cycleEdit

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two partial solar eclipses of Solar Saros 117.
