Look up to the night sky Sunday night,
September 27th, and watch a type of outer space light show that
hasn’t happened in more than 30 years—a supermoon combined with a total lunar
eclipse.
The moon will pass through the earth’s shadow
for more than an hour. The moon will remain dimly visible and have a red or
copper hue during the eclipse. For that short time it will be called a blood
moon because of its brief color change.
During the full eclipse, the moon will be at
its perigee—the closest point it passes near the earth during its oval orbit.
That’s when the moon will appear 14% larger to the naked eye and be called a
supermoon. A total lunar eclipse and a supermoon are separate occurrences that
rarely occur together. This won’t happen again until 2033.
NASA engineers issued a report pinpointing the
time of the lunar eclipse. The larger-than-normal supermoon will begin to dim
at 8:11 p.m. Eastern Daylight Time (EDT). The earth’s shadow will fall across
the moon at 9:07 p.m. At 10:11 p.m. EDT the blood moon will be in total eclipse
for 12 minutes. The NASA report describes the moon as having a ghostly copper
color until it emerges from the earth’s shadow.
All 72 minutes of the celestial event will be
visible in eastern and central North America, all of South America and parts of
Western Europe.
The Lunar Reconnaissance Orbiter (LRO), NASA’s
star gazing satellite, will record every second of the eclipse. Scientists can
use the LRO to study moon measurements, such as surface temperatures, that are
not easily available during the normal phases of the moon.
Star observers have studied the movement of
the moon since ancient times. Many cultures attached superstitions to the moon’s
temporary disappearances during eclipses. A few of those irrational fears
included stories that the moon was attacked by hungry demons or an angry sun.
Some stories were based on the sun and moon quarrelling. Some modern stories
about moon eclipses describe them as omens of death and worldwide destruction.
One superstition all of us could use is to
keep our fingers crossed that the night sky will be clear on Sunday. That way
we can get a view of the supermoon eclipse. Otherwise we’ll have to wait until
2033 when it happens again.
