Blood Moon Identification in NASA reports Often I look at NASA's Eclipse Web Site. More specifically, I often look at the Index to Five Millennium Catalog of Lunar Eclipse. How can I tell if an eclipse results in a "blood moon"? I know not all lunar eclipses result in a blood moon, but I do know that some do. So how can I know if one is from looking at it? A blood moon is the phenomenon whereby the moon in total eclipse appears reddish in color as it is illuminated by sunlight filtered and refracted by the earth's atmosphere. (Google)

Edit:

James K says this question may be a duplicate of another question. I want to know how to identify "blood moons" from looking at NASA's reports. The other question is more general. However the answer may be the same.
"Blood moon" is not a term used scientifically. Therefore look for total lunar eclipses. 

As some light is diffracted by earth's atmosphere, the moon is not entirely black but appears red. (Blue light is scattered, see why is the sky blue).

All total lunar eclipses will show a reddish colour. The brightness may vary according to the state of the atmosphere but the moon will never be black, or any other colour.
