Signs in the Moon

My Way News - Supermoon plus eclipse equals rare sky show Sunday night
My Way News reports: "Get ready for a rare double feature this weekend, starring our very own moon. A total lunar eclipse will share the stage with a so-called supermoon Sunday night or early Monday, depending where you are. That combination hasn't been seen since 1982 and won't happen again until 2033. [...] This weekend's eclipse marks the end of a tetrad, or series of four total lunar eclipses set six months apart. This series began in April 2014. The 21st century will see eight of these tetrads, an uncommonly good run. From 1600 to 1900, there were none."
