Early risers can watch the current cycle of moon phases come to an end in the morning sky this week. During the last few weeks, the moon has waxed from a thin crescent, visible in the western sky during evening twilight on Oct. 21, to a full moon on Nov. 2. After passing Mars this morning, the last quarter moon will shrink to a thin crescent and pass Saturn and Venus later this week. The moon will then sink into the glare of the sun and become a new moon on Nov. 16.
Look for a thin waning crescent Thursday morning about 60 minutes before sunrise, high in the southeastern sky. The thin crescent will be located about 7 degrees to the right of Saturn.
By Saturday morning, about 30 minutes before sunrise, a wafer-thin crescent will sit about 15 degrees above and to the right of dazzling bright Venus. Our "morning star" will only sit about 7 degrees above the east-southeastern horizon.
