Full Hunter's Moon

The first moon after the Harvest Moon is the Hunters Moon, so named as the preferred month to hunt summer-fattened deer and fox unable to hide in now bare fields. Like the Harvest Moon, the Hunters Moon is also particularly bright and long in the sky, giving hunters the opportunity to stalk prey at night. Probably because of the threat of winter looming close, the Hunters Moon is generally accorded with special honor, historically serving as an important feast day in both Western Europe and among many Native American tribes. Note that some years the Harvest Moon falls in October instead of September. The Hunters Moon of October is sometimes referred to as the Blood Moon or Sanguine Moon, as the Native Americans named this bright moon for obvious reasons. Other names for this full moon include the Travel Moon and the Dying Grass Moon. A full moon is a lunar phase that occurs when the geocentric apparent longitudes of the sun and moon differ by 180 degrees; the moon is then in opposition with the sun. At this time, as seen by viewers on earth, the hemisphere of the moon that is facing the earth (the near side) is fully illuminated by the sun and appears round. Only during a full moon is the opposite hemisphere of the moon, which is not visible from earth (the far side), completely unilluminated. As a lunar month is about 29.531, the period between full moons can be either 29 or 30 days.
