This composite image of the total lunar eclipse on September 28, 2015, captured the Moon during totality. Earth's umbra at the Moon's distance spans about 9,000 kilometers or ~2.6 lunar diameters.
"A full 62 luxurious minutes of totality. That's what we can expect on the night of January 20–21 when the Full Wolf Moon does a slow dance through Earth's umbra (the innermost region of the shadow). The last total lunar eclipse over the Americas took place in the wee hours of January 31, 2018. This one will be more user-friendly for Western Hemisphere observers as it happens during evening hours. If you're adept at comparing full Moon sizes, examine the Moon during the eclipse. Does it appear larger than normal? In fact it is! Perigee, when the Moon is closest to the Earth, occurs only about 14 hours after maximum eclipse. That makes this a supermoon, defined as a full Moon that comes within 90% of its closest approach to Earth. ..."
