Where is the Moon tonight?

The Moon is a waning crescent and 18 percent lit at Wed 7 Oct 00:00. Tonight it rises in the east-northeast at Wed 7 Oct 01:46. It is highest at Wed 7 Oct 05:33, 43° up in the east-southeast. New, first quarter, full and last quarter each cover about 22.5 degrees of the cycle; crescent and gibbous cover about 67.5 degrees each. So "first quarter" here means 40 to 60 percent lit, and another almanac may name the night differently.
