Moon at First Quarter

Thursday 12th Sep 201316:10

The Moon will reach first quarter – roughly a week after passing new moon, and a week before reaching full moon. At this point in its monthly cycle, it is visible in the late afternoon and evening. Over subsequent nights it rises a little under an hour later each day to become prominent for much of the night as it approaches full moon, a week after first quarter.

On this occasion the Moon will lie at a declination of -19°40′ in the constellation Ophiuchus, and so will appear highest in the southern hemisphere. It will be visible from all latitudes north of 60°N.
