SUN = { # http://www.timeanddate.com/worldclock/aboutastronomy.html
    "Current.AstroTwilight.Start":  "N/A", # Astronomical Twilight : starts (Astronomical twilight is the time when the center of the sun is between 12° and 18° below the horizon. From the end of astronomical twilight in the evening to the beginning of astronomical twilight in the morning, the sky (away from urban light pollution) is dark enough for all astronomical observations.)
    "Current.AstroTwilight.End":    "N/A", # Astronomical Twilight : ends
    "Current.NauticTwilight.Start": "N/A", # Nautical Twilight : starts (Nautical twilight is the time when the center of the sun is between 6° and 12° below the horizon. In general, nautical twilight ends when navigation via the horizon at sea is no longer possible.)
    "Current.NauticTwilight.End":   "N/A", # Nautical Twilight : ends
    "Current.CivilTwilight.Start":  "N/A", # Civil Twilight : starts (Morning civil twilight begins when the geometric center of the sun is 6° below the horizon (civil dawn) and ends at sunrise. Evening civil twilight begins at sunset and ends when the geometric center of the sun reaches 6° below the horizon (civil dusk).)
    "Current.CivilTwilight.End":    "N/A", # Civil Twilight : ends
    "Current.Sunrise":              "N/A", # Sunrise (Sunrise or sun up is the instant at which the upper edge of the Sun appears on the horizon in the east.[1] The term can also refer to the entire process of the sun crossing the horizon and its accompanying atmospheric effects.)
    "Current.Sunset":               "N/A", # Sunset (Sunset or sundown is the daily disappearance of the Sun below the horizon in the west as a result of Earth's rotation.)
    "Current.Sunrise.Azimuth":      "N/A", # Azimuth : Sunrise (degree) (The solar azimuth angle is the azimuth angle of the sun. It is most often defined as the angle from due north in a clockwise direction.)
    "Current.Sunset.Azimuth":       "N/A", # Azimuth : Sunset (degree)
    "Current.Sun.Length":           "N/A", # Length of day : This day (0h 0m 0s)
    "Current.Sun.Diff":             "N/A", # Length of day : Difference (-+ 0m 0s)
    "Current.Solarnoon.Time":       "N/A", # Solar noon : Time (Solar noon is the moment when the Sun transits the celestial meridian—roughly the time when it highest above the horizon on that day. This is also the origin of the terms ante meridiem and post meridiem as noted below. The Sun is directly overhead at solar noon at the equator on the equinoxes; at Tropic of Cancer (latitude 23° 26' 22? N) on the June solstice; and at Tropic of Capricorn (23° 26' 22? S) on the December solstice.)
    "Current.Solarnoon.Altitude":   "N/A", # Solar noon : Altitude (degree)
    "Current.Solarnoon.Distance":   "N/A", # Solar noon : Distance (10**6 km)
    "In.Broad.Daylight":            True,  # en plein jour ou en pleine nuit

MOON = { # http://www.timeanddate.com/worldclock/aboutmoonrise.html
    "Current.Moonrise":                  "N/A", # Moonrise (Moonrise is the first appearance of the Moon over the Earth's horizon. It may also refer to:)
    "Current.Moonset":                   "N/A", # Moonset (reverse of moonrise)
    "Current.Moonrise.Azimuth":          "N/A", # Azimuth : Moonrise (degree) (The azimuth displayed is the horizontal direction of the Moon at moonrise or moonset, at the times displayed in the Moonrise and Moonset columns. As on a compass, the azimuth is measured in degrees, with 360 in a full circle, counting in a clockwise direction starting from north. North has an azimuth value of 0 degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees. A small arrow is displayed after the azimuth value to indicate the map direction where the Moon will rise or set (for a map where north is upward).)
    "Current.Moonset.Azimuth":           "N/A", # Azimuth : Moonset (degree)
    "Current.Moon.Meridian.Time":        "N/A", # Meridian Passing : Time (shows the local time of the moment when the Moon's position will be above the horizon either directly north or directly south (except for Polar Regions, where the Moon might be down all day during the winter). For locations near the equator, the Moon can be right over one's head, at the point nearest the zenith position (altitude 90 degrees).)
    "Current.Moon.Meridian.Altitude":    "N/A", # Meridian Passing : Altitude (degree) (shows the altitude of the Moon's center above the ideal horizon at the passing time. Typically this is the highest position it reaches in the sky that day (except near the South and North Poles, where the altitude often increases or decreases all day and night). The altitude takes into account typical refraction in the Earth's atmosphere. If the Moon is below the horizon all day, the altitude will be labeled "below.")
    "Current.Moon.Meridian.Distance":    "N/A", # Meridian Passing : Distance (km) (is the distance from the Earth's center to the Moon's center in kilometers. To compare, the Earth has an equatorial diameter of 12,756 km and the Moon an equatorial diameter of 3,476 km.)
    "Current.Moon.Meridian.Illuminated": "N/A", # Meridian Passing : Illuminated (percent) (fraction of the Moon illuminated at the meridian passing.)
    "Current.Moon.Phase":                "N/A", # Phase of moon and time (The "Phase" column will be displayed only on days when a certain Moon phase event occurs. The local time will be displayed after one of these Moon phases:)
