Where Is The Moon ver. 0.1 visualizes today's/tonight's or simulated Moon's phase (as viewed from the northern hemisphere) and position of the Moon in relation to the Earth and the Sun (from above the north pole). Additionally, it displays some lunar astronomical parameters. Using control panel you can observe future or past Moon's phase, location and parameters.

Controls:
• - 'Play Animation' simulates UTC time flow according to combobox settings
   
• - 'One Step' button moves the UTC clock one step ahead or backwards according to combobox settings
   
• - Sets current time. Back to today's Moon.
   
• 'Next New Moon','Next First Quarter', 'Next Fool Moon', 'Next Third Quarter' buttons - set simulated time to the specified Moon's phase.
• 'Set UTC Time' allows you to set UTC time.

Parameters:
• Moon Phase - name of the Moon's phase (New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent)
• Illumination - fraction of the Moon's disk illuminated by the Sun (units: percent, 0% - New Moon, 100% - Full Moon, 50% - I and III Quarter)
• Moon Earth Distance - the distance between the Moon and the Earth. It varies from around 356400 km (perigee) to 406700 km (apogee). (units: kilometers [km], miles [mi], astronomical units [AU])
• Moon Ecliptic Longitude - ecliptical position of the Moon, an angle between zero point of longitude, also called first point of Aries (the point where Sun occurs during the Vernal Equinox) and the Moon measured eastwards. (units: degrees)
• Sun Ecliptic Longitude - ecliptical position of the Sun, see above. (units: degrees)
• Moon Sun Elongation - an angle between the Sun and the Moon. (units: degrees)
• Moon Ecliptic Latitude - location of the Moon. Angular distance between ecliptic (apparent path of the Sun across the celestial sphere) and the Moon. Positive to the north, negative to the south. (units: degrees)
• Right Ascension of the Moon - coordinate of a point on the celestial sphere using the equatorial coordinate system. Right ascension is the celestial equivalent of longitude. RA is measured towards the east. (units: HMS - hours, minutes, seconds - 24 hours is equivalent to a full circle)
• Declination of the Moon - second coordinate on the celestial sphere, comparable to latitude. Angular distance between celestial equator (great circle on the celestial sphere, in the same plane as the Earth's equator) and the location of the Moon. (units: degrees)

Note:
• Algorithms implemented in the 'Where is the Moon' tool are based on Jean Meeus' Astronomical Algorithms (Willmann-Bell, Inc., Richmond, 1998)
• 'Where Is The Moon' online tool requires browsers with CSS3 support that means you could not be able to run all its features on older versions of internet browsers.
• The distances, size of the Moon and size of the Earth shown on the visualization are not drawn to scale.
• Stars in the background are generated randomly, they are only to beautify the page.
