A reminder: total lunar eclipse on Thursday evening.
In Jack Horkheimer's "Star Hustler" episode last week he mentioned a
luminousity scale used to rate the brightness of a lunar eclipse. I did
not catch the name (something like daw-john??), but the scale goes from
L-0 for darkest to L-4 for brightest. He quickly went through the visual
criteria used to do the rating.Would anyone have more information on
this scale or a reference?
I checked my Astro library and a couple of web sites.

By the way, according to Horkheimer, this is the last eclipse visible in
N. America until 2000. Weather forecast here is is poor.
