Keep your eyes to the sky on Sunday evening for the most widely visible lunar eclipse in the United States since 2014. As a special treat it will also be a supermoon, meaning it will slightly closer to Earth than normal, giving it a larger appearance.
The full eclipse, will entirely cover the moon for an hour and two minutes and will be the last lunar eclipse until 2021. The partial phase of the eclipse begins at 9:36 pm Eastern time on Sunday the 20th. The full eclipse — characterized by the blood-red shadow cast on the moon — begins at 11:41 pm Eastern and finishes at 12:43 am on Monday the 21st.
