xmoontool - Moon For The Sun / Werewolf Early Warning System
Tedious Technical Credits
Xmoontool is a Xwindows application which displays information about the moon in
real time. When closed (iconic) it displays a graphical representation
of what the moon would look like right now if you were to go outside and
look at it. (Go on, try it, the fresh air may do you some good). When
the window is open, the same image of the moon is displayed in the upper
right of the window, along with more verbose information about both the
moon and the sun (the bright yellow thing in the sky, not the thing youre
staring at right now. Its not a good idea to stare at the bright yellow
thing). The open window display is updated approximately once
per second, the icon is updated every two minutes.
Xmoontool will run on both monochrome and color displays. Unless explicity told to
run in either the monochrome
(-m) or the color
xmoontool will automatically select the appropriate mode. On color displays,
the moons face is rendered in eight colors in both the icon and the
open window. The darkened portion of the moon is visible on color displays
as dark shades of blue. On monochrome displays, only the illuminated
portion of the face is drawn in.
As an extra added bonus for users of
color displays, the Apollo 11 Commemorative Red Dot has been added to the
face of the moon at the approximate location of Tranquility Base, to
mark the 20th anniversary of An Historic Event.
The image of the moons face used by
xmoontool, especially the color version, is quite accurate. It was rendered on an
Amiga by Joe Hitchens, an artist of no small talent, from an illustration
in an astronomy textbook.
If invoked with the
xmoontool will start up in test mode. In test mode, the tool warps through time,
updating the display as fast as possible, skipping approximately one
hour per cycle. A menu is available on the tool, for both the icon and
the open window, which will let you switch in and out of test mode at will.
This is whats known as a cheap thrill, and can provide endless hours of
entertainment (if youre easily entertained).
-U effects the moons and the suns distances to be expressed in (statute)
miles instead of the default kilometers.
For those who are lycanthropically inclined, the open window tells
you when the next full moon will occur. This may or may not be something
youll want to know.
TEDIOUS TECHNICAL CREDITS
Believe it or not,
xmoontool uses some actual science and even authentic mathematics. If youre into
that sort of thing, you might like to know that the following books
were used by the original author to create
"Practical Astronomy With Your Calculator" by Peter Duffett-Smith,
Second Edition, Cambridge University Press, 1981.
"Astronomical Formulae for Calculators" by Jean Meeus, Third Edition,
"Planetary Programs and Tables from -4000 to +2800" by Pierre Bretagnon
and Jean-Louis Simon, Willmann-Bell, 1986.
"Celestial BASIC" by Eric Burgess, Revised Edition, Sybex, 1985.
This one was used by Joe to render the moon image and by me to locate
the Apollo 11 landing site:
"Astronomy: From the Earth to the Universe" by Jay M. Pasachoff,
Second Edition, Saunders College Publishing, 1983
