A total lunar eclipse will occur this Wednesday morning starting at 6:48. As it’s the second full moon of the same month, it’s called the “Blue Moon”. This one is being called the “Super Blue Moon” because its the first one to occur over the Americas in 150 years! A lunar eclipse is a very safe event to look at as the moon simply slides into the Earths shadow. Light refracted through Earth’s atmosphere turns the surface of the moon red, much like we see red sunsets.
