Incorrect @ Luke

The autumn we are all referring too is the meteorological autumn that we experience here on earth and 5 miles above out heads, a season that involves weather and plants and animals

The equinox that just so happens to use the words autumn and summer refers to astronomy outwith the earths atmosphere and refers to when day and night lengths are equal

If you start using astronomical measures for seasons you have the silly situation were December the 20th is still autumn

Autumn is Sept, Oct and Nov
