LunarPhase is a utility for Win 95/98/NT which provides a range of information on the Moon and, to a lesser degree, the Sun, graphically displaying the current phase of the moon (in real time).

It uses the user's geographic location, Timezone and Daylight Savings Time (set on the Configuration screen) for its calculations, so these must be set up correctly. All times displayed (and printed) are in local time.

LunarPhase Main Features:

---

Moon

Graphically displays the current phase of the moon in real time

Displays the times and dates of the major lunar phases for the month

Displays the illuminated fraction of the lunar disk as a percentage in real time

Displays the current age of the moon (since the last New Moon) and its distance from Earth in real time

Provides realtime position of the moon in both RA/Dec and Alt/Az coordinates

Provides the moon's parallax and its visible diameter (in arcminutes) in real time

Displays a calendar of lunar phases for each day in the selected month

Displays a Lunar Visiblility diagram for the month showing when the moon is above the horizon

Displays a Daily View diagram for the moon showing when the moon is above the horizon and hourly Azimuth and Altitude figures

Calculates the times and dates of the next Apogee and Perigee

Calculates the Position Angle of the moon's bright limb in real time

Calculates the moon's Phase Angle in real time

Calculates and displays Moon's Rise, Set and Transit times

Calculates the circumstances of lunar eclipses and whether they're visible from your location

Calculates the dates of lunar eclipses between two given years

Displays the names of Full Moons throughout the year, including Blue Moons [second full moon in a month]

Set the time and date to that of a major lunar phase (New Moon, First Quarter, etc.) by clicking on the phase icon or phase data and time

Set the time and date to that of an eclipse by clicking on the eclipse date in the eclipse details window

Blue moons are indicated by a blue full-moon icon in the major phases window.

Displays lunar librations in latitude and longitude corrected for your location (Topocentric)

Displays Selenographic CoLongitide and Position Angle of the moon's Axis

Displays a list of sunrise and sunset times at various lunar features (both near-side and far-side) for the month

Provides a database of lunar features which is used in the calculation of sunrise and sunset at those lunar features. 1961 lunar features are provided with the software

Sun

Provides realtime position of the Sun in Alt/Az and RA/Dec corordinates in real time

Calculates and displays Sun's Rise, Set and Transit times

Shows the (compass) positions of the rising and setting sun for your location

Twilight

Calculates and displays Start and End times for Civil, Nautical and Astronomical Twilight

Printouts

Calendar printout for the selected month which includes for each day: the lunar phase (graphically), lunar rise/set/transit times, solar rise/set/transit times and the times and dates of the major lunar phases in the month. The user selects which of these appears on the printout.

Tabular printout of all lunar, solar and twilight data.

Printout of Lunar Visibility diagram.
