A penumbral lunar eclipse took place on 7 July 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 22 July 2009.
