2014 April 28
Time Lapse of a Total Lunar Eclipse

Mt. Lemmon SkyCenter,
U. Arizona
Explanation:
Why would a bright full Moon suddenly become dark?
Because it entered the shadow of the Earth.
Almost two weeks ago this exact event happened as the Moon underwent a
total lunar eclipse.
That eclipse,
visible from the half of the Earth then facing the Moon,
was captured in
numerous
spectacular
photographs and is depicted in the
above time lapse video covering about an hour.
The
above video,
recorded from
Mt. Lemmon Sky Center in
Arizona,
USA,
keeps the Earth shadow centered and shows the Moon moving through it from west to east.
The temporarily
good alignment
between Earth, Moon, and Sun will show itself again
tomorrow --
precisely half a moon-th
(
month) later -- when part of the Earth will pass through part of the new Moon's shadow.
