To work out the visibility of the celestial item for an observer at a specific time and place within the Earth, the coordinates of the item are needed relative to some coordinate technique of the present day. If coordinates relative to some other date are utilised, then that will trigger glitches in the outcome. The magnitude of Those people glitches increases with the time difference between the day and time of observation along with the day from the coordinate technique applied, because of the precession from the equinoxes.
An epoch in astronomy is usually a reference time utilized for consistency in calculation of positions and orbits. A common astronomical epoch is J2000, that's midday on January one, 2000, Terrestrial Time.

(Occasionally the word 'equinox' may very well be utilized by itself, e.g. exactly where it is apparent within the context to buyers of the data where kind the considered astronomical variables are expressed, in equatorial sort or ecliptic form.)
In the event the higher bound was expanded in later on variations, the lessen bound was left exactly the same to maintain backward compatibility with techniques that applied it for website a datum.[28]
