LunarPhase is a utility 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).

LunarPhase uses the users 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

Here are some key features of "LunarPhase":

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 moons 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 moons bright limb in real time
· Calculates the moons Phase Angle in real time
· Calculates and displays Moons Rise, Set and Transit times
· Calculates the circumstances of lunar eclipses and whether theyre 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 moons 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 Suns 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.
· Printout of Daily View diagram and data.
Other Features
· Data for any date can be generated using inbuilt calendar
· Selection of any time during the day, including reset to current time and date
· Can synchonise your PCs clock with an online atomic clock
· View moon as seen through binoculars, an astronomical telescope or a telescope that uses a diagonal
· Day order on calendar can be changed
· Tabular function provides a list of lunar rise/set/transit times, moons illuminated fraction, solar rise/set/transit times and Start/End times for Civil, Nautical and Astronomical Twilight for the selected month on one comprehensive screen
· Displays Local Sidereal Time
· Provides links to online lunar websites
· Popup window displays Day Number, Week Number (and Day No./Week No. in ISO format), Julian Day and number of days until Christmas
· A new toolbar item pops up a window with the times and dates of the Equinoxes and Solstices of the the selected year, and their durations.
· Displays the date of Easter Sunday for the selected year.
