Moon 1.0d3 for Newton

-------------------

This is a simple program to graphically display the phase of the moon for
any date you choose. You can also tap the "Next Qtr" button to display the
occurrence (local time) of the next quarter moon after the selected date.

Note that all times are corrected for your location relative to GMT
(Greenwich Mean Time), so the actual date on which a lunar event occurs at
your location may differ by +/- 1 day from the nice little moon pictures
that you see in many printed monthly calendars, depending on whether it's
already tomorrow (or still yesterday) in England at that time. :-)

This program is provided "as is". No warranty is expressed or implied.
It is free of charge, and may be freely distributed.


WHAT'S NEW IN 1.0d3:

- A new, more accurate algorithm for determining the moon phase,
  based on public domain Unix sources by Alan Silverstein and John Walker,
  which use routines given in "Practical Astronomy With Your Calculator" by
  Peter Duffett-Smith, Second Edition, Cambridge University Press, 1981.

- The moon view takes up less screen area, displays more information,
  and can now be dragged around.

- The current state is remembered when the view is closed and re-opened.

- Click the up and down scroll arrows to advance in yearly increments.


FUTURE IMPROVEMENTS:

Support "Overview" to display quarterly phases surrounding the selected date.
Print calendar with phase info. Reduce view sizes. Display secondary textual
information in a "protoGlance" type of view. The moon view can perhaps shrink
down to an icon, or install itself as a button on the status bar. It may
even be possible to extend the Dates application somehow, integrating Moon's
functionality, rather than keeping it as a separate "application" in the
Extras drawer.
