While total lunar eclipses are always spectacular, the one on May 26, 2021, promises to be particularly memorable given that it coincides with a supermoon. This means that the Moon — which will be at perigee, or its closest distance to Earth — will appear about 7 percent larger and 15 percent brighter than a standard full Moon. The eclipse will be most visible from the western parts of the Americas, Australia and New Zealand, and Eastern Asia. In the US, the best views will be reserved for Hawaii, Alaska, and the western states.
