The Second Clock

The second Clock shows also the Moon. Sun and Moon are moving in the Ecliptic. In reality the Moon can be up to 5 degrees above and below the ecliptic. The place where the Moon crosses the ecliptic is called a lunar node . The lunar nodes are the points where the Moon crosses the ecliptic (which is the apparent path of the Sun across the heavens, against the background stars). The ascending node is where the moon crosses to the north of the ecliptic. The descending node is where it crosses to the south. The Moon moves in a elliptical path around the earth, so the time it takes is always different. In this clock the Moon moves in an average time. The Sky is moving in 23h 56m 3.93s, should be 23h 56m 4.09s. The Moon is moving in 24h 50m 31.5s, should be 24h 50m 28.3288s. After some years the Moon has to be adjusted! The disc of the Sun covers the difference between mean and real Sun. At the photo it is almost full Moon. The month is September. Every day the Sun will be a little lower above the horizon. In fact there is a lot more to see!
