The Northernmost Last Quarter Moon

October 4th, 2015

The Moon reaches last quarter today, in the constellation of Gemini the Twins. Just as the most recent first quarter Moon was the southernmost of the year, this last quarter Moon is actually the northernmost. The first quarter Moon occurred in Sagittarius, the southernmost constellation, and now, half an orbit later, the Moon has moved through half the sky and is now in Gemini, the northernmost constellation.

Since the last quarter Moon is due south at sunrise, you’ll see it at its highest at that time. The Moon takes roughly four weeks to orbit the Earth – a convenient number as it means the Moon will turn new in about a week. In two weeks from now, the first quarter Moon will appear due south in the evening sky – but this time, at sunset.
