Moonbow is also a fairly common name for an early-phase waxing moon, a couple days out of its new phase, before it fills out to first quarter. During these few days, the visible edge of the moon seems to form the outline of a bow, with the 'string', if you could see it, running from tip to tip. This moon is also called a huntress moon, Diana's bow, or an Artemis moon, with the though being that the bow formed by the moon belongs to Diana/Artemis, goddess of both the hunt and the moon.
