A partial lunar eclipse on June 4, 2012, was one of three events that were visible from the western United States within a span of 16 days. This partial eclipse of the Moon occurred only a couple of weeks after the May 20, 2012, annular eclipse of the Sun, and just a day before the June 5, 2012, transit of Venus. During the partial eclipse, nearly 2/5 of the Moon entered the dark umbral shadow of Earth. The Moon passed north of the Earth's shadow, and as a result, it was the southern portion of the Moon that dipped into the Earth's shadow. In this image, north is to the right. This was the only lunar eclipse in 2012, except for a so-called penumbral eclipse on November 28, 2012. Because the Earth's penumbra shadow is tenuous, it is usually difficult for a casual observer to even notice when the Moon passes through the penumbra, and for that reason I did not count the penumbral eclipse of the Moon.
This image was taken with a Takahashi FCT-150 telescope using a Canon EOS Digital Rebel SLR camera from my backyard in Scottsdale, Arizona.
