Tomorrow, 26 May 2021, there will be a Blood Supermoon Total Lunar Eclipse. It will be visible from southeast Asia, across the Pacific, to the southwest Americas.
“Blood” refers to the color of the Moon during full eclipse. Supermoon means that the Moon is closer to the Earth in its slightly elliptical orbit, and so appears larger.
At APOD, there is a quick time-lapse video of an eclipse from 2018.
