This evening at 8:11 pm the full moon of the autumn equinox will start darkening until around 10:00 when it is completely shaded by the Earth’s shadow. This happens when the Earth is positioned precisely between the sun and the moon. It causes the moon to appear about 14 percent larger and 30 percent brighter than normal. It will also change color because longer red wavelength of sunlight trickle around the edges of the planet making it appear reddish. The last Super Moon eclipse was in 1982. It won’t happen again until 2033. If it’s cloudy or your windows face the wrong direction, don’t fret. You can watch it live stream from NASA TV.
