Bad choice for my presentation!

Needed a lot of research such as:

Moon Observations The Moon (Movies and the Web)

Researching the Web brings language issues:

Such as:


Such as:

Is someone who is observing the moon a Lunatic


Such as:

Is someone who is observing the moon a Lunatic

While Observing the moon – Mooning?

A Mooney M20C Airplane

Some Lunatic is attempting to set a world record in Mooning

Here in Brussels

Annual mooning of the Amtrac train in S. California

Even Santa tried to moon

Concluded that Larry did not want a presentation on how to observe those kind of moons

Went back in time more than a century attempting to learn about the basics of the moon

A study of the Sky (1896); Herbert A Howe:

The same book that mentioned the panic in Atlanta with Comet 17P/HolmesIn 1892


Alexander from Humbolt:

People from Asia Minor say the moon exhibits a reflection of earth as if it were a mirror




This would be great: We could use Google Earth as a guide and map to observe the moon




In the minds of many, a human figure is outlined:Judas Iscariot

Man in the Moon


Alexander from Humbolt:People from Asia Minor say the moon exhibits a reflection of earth as if it were a mirror

In the minds of many, a human figure is outlined:Judas Iscariot

The casual onlooker perceives a human face with eyes, nose and mouth.

Woman need their place also!!

Who said there was no life on the Moon? Rabbits can jump pretty far!

And Frogs can jump far too!!!

And Brother Toad is very close…….

But how Crabs swim to the Moon is a secret!!Primarily Pacific Region

The Phases of the Moon in a diagram

Observing the Moon

Constellations and Stars move across the sky in yearly cycles from East to West

The Moon’s sidereal orbit takes 27.3 days The Moon’s phase takes 29.5359 days, The Moon moves each day approx 12

degrees east against the night sky Optimal Observation points of interest on the

the moon change approx. 12 degrees each day.

Limiting conditions for optimum observation during a given month

Movement of the Morning Terminator from 1/19/2008 12:00 – 24:00 ET

Locations on the moon are identified in:

Selenographic coordinates Moon axis runs through the North and South

Poles Lunar Equator Prime meridian runs through apparent center of

the disk with both longitude and latitude libration O

Coordinates are expressed in North and SouthEast and West. (sometimes you might see + and -

signs

Selenographic Coordinates

Selenographic Colongitude: Points of Sunrise on the Moon Location of Morning terminator in degrees

west from the Prime Meridian Sunrise at Prime Meridian concurs with

First Quarter Goes from O-360 degrees

Anything >90° West or East not visible from Earth, with the exception of Libration

Libration

Orbit of the moon is elliptical Rotation is constant Speed is sometimes faster, sometimes slower

Libration

Orbit of the moon is elliptical Rotation is constant Speed is sometimes faster, sometimes slower So the moon is:

Sometimes a little ahead, sometimes a little behind

Libration

Orbit of the moon is elliptical Rotation is constant Speed is sometimes faster, sometimes slower So the moon is:

Sometimes a little ahead, sometimes a little behind

Moon’s orbit is inclined to Earth’s orbital plane Appears to nod up and down

Net exposure 7 53 East and West; 6 51 North and South

Example of Libration betweenJanuary 8 and February 4, 2008

Observing the moon

Observe details at times when they are most distinct (Highest contrast) for the object you want to see/capture (Objects near terminator)

Observing the moon

Observe details at times when they are most distinct (Highest contrast) for the object you want to see/capture

Make the moon part of a special configuration with other celestial or earth objects

Different ways to observe the moon

Observe details at times when they are most distinct (Highest contrast) for the object you want to see/capture

Make the moon part of a special configuration with other celestial or earth objects

Make many images, increasing the chance of having an extraordinary image

Day 10


Full Moon


To get the best out of your Moon observations:

Use a good Atlas

Determine when the object is visible

Use Filters to bring out contrast

Verify the Phase of the moon (Observation time)

You can observe some features during daytime

Plan the observations in advance

Anticipate what you will see
