Sunday, September 27, 2015 Supermoon lunar eclipse Supermoon: full moon that is closest to the Earth, making it look bigger in the sky. Can look up to 14% larger and 30% brighter. Lunar Eclipse: When the Earth is inbetween the Sun and the Moon, blocking the light and giving the moon its reddish color. This double occurrence (Supermoon Lunar Eclipse) will not happen again until 2033!! I am so happy I captured this.
