Starwatch: a chance to bask in earthshine

A lunar phenomenon that is sometimes called the old moon in the new moon's arms may be visible on Monday

This evening's crescent moon brings with it a good chance of seeing earthshine. This is the faint glow that appears on the unlit portion of the moon's disc. It is sometimes referred to as the old moon in the new moon's arms because of the way the sunlit crescent appears to cradle the dimmer circle.
