Notes

A region of the Moon's southern hemisphere is captured here, highlighting crater Tycho with its prominent ray pattern. Below and slightly to the left of Tycho is the tortured mass of crater Clavius, sporting a multitude of smaller craterlets within its boundary. Directly above Tycho at the upper edge of the image is the dark featured Mare Nubium. Located at a 2:30 o'clock position from Tycho near to the terminator is the large circular crater Theophilus with its multi-summited central peak. Just to the left of Theophilus is its somewhat less spectacular but equally-sized companion Cyrillus, sharing with Theophilus a common crater wall. To the right of Theophilus along the terminator is Mare Nectaris (Sea of Nectar). Following the smooth plain of Mare Nectaris north to the upper right corner of the image, a glimpse of the southern end of Mare Tranquillitatis can be seen, site of the Apollo 11 Moon landing on July 20, 1969 at 20h17m40s UT which immortalized Neil Armstrong as a modern icon of space exploration. Also in the image a short distance to the left of Cyrillus is the location of the Apollo 16 Moon landing near crater Descartes. Spending approximately 3 days on the moon, Apollo 16 astronauts John Young and Charles Duke, were the second to last crew to set foot on the Moon, that program ending with the Apollo 17 mission in December 1972.

The Moon phase was 78.1% at the time of this image..
