September 27th, 2015, late Sunday Evening, we will experience an amazingly rare event: a supermoon lunar eclipse. This means the lunar eclipse will happen when the moon’s orbit will be closest to the Earth’s surface than it has ever been, appearing 14 percent larger and 30 percent brighter than we are used to seeing it.
It will also appear in a dusty red color from the sunlight trickling around the edges of the planet and gets filtered through the atmosphere, which only lets through light with longer wavelengths.
The last supermoon eclipse was in 1982, and it won’t happen again until 2033.
It’s an event you don’t want to miss. Here’s how to get the best of it:
Peak eclipse will be at 2:47 am UT on September 28th—so, 10:47 pm ET on Sunday, September 27th.
If you’re in the eastern United States, that’s good news! You should be able to see the eclipse just fine.
The moon will start darkening at 8:11 pm Eastern time, and it will start to pass through the Earth’s dark umbral shadow at 9:07 pm. It’ll be completely shaded for about an hour starting around 10 pm.
That means the fully eclipsed moon will just be rising as viewers on the west coast tune in.
