The week of May 9-15 takes us from Day 8 to Day 15. This week we will highlight a lunar eclipse to take place on Sunday, May 15.

Total lunar eclipse or blood moonA total lunar eclipse will occur on Sunday, May 15. It is called a “Blood Moon” because of the reddish color when the Moon is in full eclipse. The entire eclipse, including the penumbral phases, will be visible in the eastern U.S. and parts of the Midwest. The entire partial and total phases (minus the beginning penumbra) will be visible in Colorado and most of the U.S. In Colorado the first bite will be taken out of the Moon at 8:30 p.m. and full eclipse begins at 9:30. The total phase will end at 10:53.


It is highly recommended that you get a copy of Sky and Telescope’s Field Map of the Moon, the very finest Moon map available for use at the telescope. It is available for $10.95 at and on Amazon. All features mentioned in this blog will be keyed to the grid on the Field Map and will look like this: Plato: [NW/D9]
