NAME
WMMOONCLOCK - Dockable Moon Phase Clock
SYNOPSIS
wmMoonClock [-display <Display>] [-bc <Color>] [-lc <Color>] [-dc <Color>] [-low] [-lat
<Latitude>] [-lon <Longitude>] [-h]
DESCRIPTION
wmMoonClock displays the current phase of the moon. Clicking on the icon brings up
different displays -- there are 5 in all. The different "pages" are;
First Page
Shows the Moon phase image.
Second Page
Shows the current Local Time (LT) and Universal Time (UT), the Moon's Age (number
of days since last new moon), the geometric (as opposed to temporal) fraction of
the way through the current lunar cyle (e.g. 50 for full moon), the fraction of the
Moon's disc that is illuminated (ratio of area illuminated to total area of disc)
and whether the Moon is (locally) visible of not (i.e. is it above the horizon?).
Third Page
Shows the Rise and Set times for yesterday (first line), today (middle line), and
tommorrow (last line). If the Moon does not rise or set on a given day a `null
time' is shown (--:--). Note that these times should still be good for high
latitude observers. Also note that there will always be at least one (--:--)
showing up per month. This is because once per month the Moon will rise (set) on a
given day but will set (rise) in the very early portion of the next day.
Fourth Page
Shows the Moon's horizon coordinates (i.e. the Altitude/Azimuth system). Azimuth is
measured in degrees CCW from due south, and altitude is measured in degrees from
the horizon up to the Moon. Distance (Dist) is measured in units on Earth radii (1
Re is about 6370km). Note that this is a local coordinate system and will not be
correct if the observer's latitude and longitude are not set correctly.
Fifth Page
Shows the Moon's ecliptic coordinates. (i.e. the Right Ascention/Declination
system). Useful for astronomers?
Many of the quantities shown will not be correct unless LT and UT are correct, and the
user specifies the proper latitude and longitude.
OPTIONS
-display <display>
Use an alternate X Display.
-bc Set background color. (E.g. #7e9e69 or blue)
-lc Set color of text labels.
-dc Set color of data values.
-low Conserve colors. For 8-bit displays, a lower-color pixmap will be used
automatically, but you can also force its use on higher-color displays if
necessary.
-lat <Latitude>
Observers Latitude in degrees. Positive in northern hemisphere, negative in
southern hemisphere.
-lon <Longitude>
Observers Longitude in degrees. Greenwich is 0.0, and longitude increases
positively toward the west. (Alternatively, negative numbers can also be used to
specify longitudes to the east of Greenwich).
-h Display list of command-line options.
