Lunar eclipses fall on a full moon by definition. This full moon was the closet to Earth full moon of any other this year. This not only makes the full moon look about 7% larger than average but also puts it deeper into the Earth's shadow during the eclipse darkening it a bit more than usual. It was further darkened due to volcanic ash from the Calbuco volcano in Chile still erupting since earlier this year. The dust and smoke injected into the stratosphere served to filter out more of the refracted sunlight bending around the earth's circumference to the surface of the moon.
