Most names of moon features have a Latin
connection. The following graphic illustration nomenclature is memory aid
in learning features on the moon.

When documenting the moon objects, use the
official Astronomical League forms. My hints for finding these objects are
just that. They are not to be used as official documents for presentation
to the AL.
The first eight objects of the first page
and the entire last page of the Astronomical League form has some fun
activities, like finding the man, woman, rabbit and cow jumping the moon
etc. I did not list these activities in the Moonwalk.
Taking a Moonwalk
A quick telescopic tour, hitting just the
highlights of the moon should include; The Alps and Alpine Valley, Strait
Range, peaks Piton and Pico, Straight Wall with Crater Birt, rays from
crater Tycho and Copernicus, the Altai Scarp, the Cobra Head close to
Schroeder's Valley, the little bear of Mare Crisium, bright crater
Aristarchus, comet crater Messier and other craters with common names
including the Craters; Picard, Billy, Catharina, Mitchell, Davy, Linne and
Walter and the Apollo landings. The very center of the moon is Sinus Medii.
These features are underlined in the enclosed list.
Man has landed on the Moon only six times:
- Twice in Mare Tranquillitatis
- Twice at the intersection of Mare Nubium,
Mare Humorum and Oceanus Procellarum
- Once in Mare Imbrium by the Apennines
- Once in the Southern Highlands West of
Mare Nectaris
Take the first step in moonwalking, become
familiar with larger features of the moon using binoculars. Finding
smaller objects with the telescope becomes easier. Some of the largest
binoculars Moon features are the Maria (or seas). These dark basaltic
features are easy to see. As a visual memory aid, I have devised a
segmented moon bug using these seas (see graphic).
Bugs need to
store nectar and reproduce. The Southern end of my bug has two Mare,
pronounced (Mar-ee) used for this purpose, Mare Nectaris (Sea of Nectar)
and, Mare Fecunditatis (Sea of Fertility).
This moon bug has a giant supply of food
and is about to take a huge bite out of the flower, Oceanus Procellarum
(Ocean of Storms ). He is therefore satisfied, tranquil and serene. His
body is composed of two segments Mare Tranquillitatis (Sea of Tranquillity)
and Mare Serenitatis (Sea of Serenity).
He has nearly useless arms near the head,
made of vapors and dreams, Mare Vaporum (Sea of Vapors) and Mare Somniorum
(Sea of Dreams). An extension above the Sea of Dreams, makes a dead finger
called, Lacus Mortis (Lake of the Dead).
The Crater Plato is his eye. His head is
comprised of both light mountains and dark seas. The teeth and bony head
structure are formed from a bright ring of mountains around Mare Imbrium.
Montes Apenninus, the Montes Caucasus and the Montes Alpes and the ridge
of mountains to the North, including Promontorium Laplace, the Jura
Mountains and Promontorium Heraclides are included. The top of his head
has a dark skullcap made from Mare Frigoris (Sea of Cold).
My bug is about to bite a flower that has
two petals full of moisture. The South end of Oceanus Procellarum (Ocean
of Storms ) is supported by the petals Mare Nubium (Sea of Clouds) and
Mare Humorum (Sea of Moisture).
The Moon bug also carries a backpack for
emergencies called Mare Crisium (Sea of Crisis).
Defining our Moon Bug has allowed us to
document 17 different AL objects on the moon. Finding the other
eighty-three using the bug and its surroundings should be easy.
