NOTES ON USING THIS LUNAR EPHEMERIS PROGRAM

Waxing phases are between New Moon and subequent Full Moon.
Waning phases are between Full Moon and subsequent New Moon.

The parallactic angle or 'tilt' of the lunar image is based on the
time zone and geographic location of the observer.

For the parallactic angle to be correct, both the given time zone and
geographic longitude must correspond correctly.  The program cannot
reliably determine the time zone offset from the longitude alone and
depends on the user to supply the correct information when using it.

When daylight saving/summer time is in effect, the time zone offset from UT
will be 1 hour less than the standard difference.
For example, -04:00 for NY City, instead of the standard -05:00

When the [Set to Now] button is clicked, the Date/Time/Zone are taken from
your local systen clock using a JavaScript function, but the latitude and
longitude remain set until changed or the cookie storing their values is
deleted or expires and usually refers to the home location of the
observer, which has to be given by the user.
