The diagram below shows the path of the Sun across the sky in Melbourne for four important dates:
- The Autumn Equinox, usually on March 21, is when the Sun rises exactly east, sets exactly west and we have approximately equal day and night.
- The Winter Solstice, usually on June 22, is when the Sun is furthest north and we have our shortest day; and longest night.
- The Spring Equinox, usually on September 23, is identical to that of March 21, except that the Sun rises 16 minutes earlier on September 23.
- The Summer Solstice, usually on December 22, is when the Sun is furthest south and we have our longest day and shortest night.
The outer circle on the diagram represents the horizon and the inner circles are lines of constant elevation, drawn at 15° intervals. The radial lines are lines of constant azimuth drawn at 15° intervals also.
The position of the Sun at each hour of the day is marked and the time indicated. All times are Australian Eastern Standard Time. Add one hour for daylight savings.
