Grab a seat outside on January 31, 2018 where you can view a total lunar eclipse of a red supermoon which is amazingly a blue moon too! It’s safe to look at a lunar eclipse as the sun is not above the horizon. If sunlight hits the moon while eclipsing it has to pass over the Earths horizon casting a red hue.
The moon will appear to be 30 percent brighter and 7 percent larger than average due to the moon’s orbit swinging in close to the earth. As it’s a second full moon within a calendar month it’s also a blue moon. The last time this occurred was March 31, 1866!

Umbra: this is the smallest circle – the sun is totally blocked by the Earth
