Notes:

Note 1:

The coordinates initially are those of Madrid (Astronomical Observatory), Spain. It was the length of the geodetic reference geographically in Spain until it was replaced with the Greenwich Mean Time (GMT) in the late nineteenth and early twentieth centuries. [Obtaining coordinates of any point]

Note 2:

To operate the applet Javascript is necessary for the browser so permits. Make sure your computer clock has the correct date and time, have low accuracy algorithms used (in any case not less than 0.05 degrees), if needed more accuracy is recommended to consult the NOAA solar calculator or Acquire the Dialist's Companion (ephemeris calculator NASS).

Description of the items in the table

1. Legal hour - It's time to make our watches. Volver/Return

2. UTC hour - Is Coordinated Universal Time, formerly known as Greenwich Mean Time. Volver/Return

3. Civil time - mean time is referred to the meridian of the place. Most often used to specify the directories astronomical ephemeris. Volver/Return

4. Solar time - It's time to mark a sundial that has not applied any correction.. Volver/Return

5. Sidereal time - is the time elapsed since the last time a point in the sky called First Point of Aries ran over our meridian. By referring to the stars sidereal days and hours are somewhat shorter than the days and hours of sunlight. Volver/Return

6. Italic Time - The time elapsed since the last sunset. Subtracting from 24 gives us the time remaining to put the Sun. Volver/Return

7. Babylonian Time - The time elapsed since the last sunrise. Volver/Return

8. Temporary time - Also called historic moment, calculated by dividing the lighting time in twelve equal hours and the time of darkness in another twelve hours equal. The temporary one-hour duration varies depending on the day of the year as well as night or daytime.. Volver/Return

9. Canonical hour - is the time to mark a sundial oriented perpendicular meridian with its gnomon and hour lines equally spaced. The name comes from this system was formerly used in monasteries to determine the hours of the monastic offices (which should be strictly temporary.). Volver/Return

10. Longitude - is the longitude (west negative) where the Earth where the Sun is exactly at the zenith.. Volver/Return

11. Ecliptic longitude - angular distance is taking the Sun as the center, which is between the point where it is now the Earth on its orbit and the point was to get the spring (Vernal Point).. Volver/Return

12. Ascension - is the projection on the equatorial plane of the ecliptic longitude. For practical reasons, measured in hours, it also indicates the sidereal time it takes the Sun late on the first point of Aries. Volver/Return

13. Declination - This is the latitude (positive north) where the Earth where the Sun is exactly at the zenith. Volver/Return

14. Equation of time - is the difference between the time marked by a mechanical clock and a sundial is fixed in length or, what is the same, time must be added to a sundial to show civil time . Due to the tilt of Earth's axis and the non-uniform motion in its orbit around the Sun, this amount is not zero and variable depending on time of year. It is measured as the delay of sun at 12:00:00 hours passing through the reference meridian. It is noted that this convention is opposite to that of the astronomers who measured the EdT as progress rather than a delay. Volver/Return

15. Elevation - The height that has the sun on the horizon, measured in degrees. Volver/Return

16. Azimut - the horizontal direction is found on the Sun is measured in degrees from the South to the West in the Northern Hemisphere and from the North to the East in the Southern Hemisphere. Volver/Return

17. Period of sunshine- is the time from dawn to dusk in the current day. Volver/Return

18. Maximum elevation - is the highest point it reaches the Sun today, measured in degrees. Volver/Return

19. Alba - the moment when the center of the sun rising over the horizon. Volver/Return

20. Noon - The moment when the Sun's center passes over our meridian. Coincides almost exactly with the time it reaches its maximum elevation. Volver/Return

21. Sunset - The instant the center of the Sun sets below the horizon. Volver/Return

22. Azimut at sunset - is the horizontal direction of the point where today the sun sets. Volver/Return

23. Gregorian date - the current date is expressed according to ISO. Volver/Return

24. Julian Day - is the number of days since noon UTC on the first day of January of the year 4173 BC. It is widely used to make astronomical calculations. Volver/Return
