07/19/2016 – Ephemeris – The bright Moon is seen low in the summer
Ephemeris for Tuesday, July 19th. Today the Sun will be up for 15 hours and 6 minutes, setting at 9:22, and it will rise tomorrow at 6:16. The Moon, at full today, will rise at 9:00 this evening.
In the summer time the moon appears to be seen low in the south. If you can remember back six month to winter and where the bright moon was then. It was very high in the sky then. The reason for the difference in altitude of the bright moon is that the Moon follows closely the Sun’s yearly track against the stars. That track is the ecliptic, along which the constellations of the Zodiac lie. The Moon’s own orbit of the Earth departs from that by five degrees. Tonight the Moon will be about 3 degrees, or 6 Moon diameters above of north of that line. The full Moon happens to be in the same place, plus or minus up to five degrees north or south of where the Sun was 6 months ago or will be 6 months hence.
