The prefix "J" indicates that it is a Julian epoch.The previous standard equinox (and epoch) was B1950.0, with the prefix "B" indicating it was a Besselian epoch. Since that time Julian equinoxes/epochs have been used.
Novices are sometimes confused by finding that the Earth's rotational North pole does not point quite at the J2000 celestial pole at the epoch J2000.0; the reason is that the true pole of epoch nutates away from the mean one. The "J" in the prefix indicates that it is a Julian equinox/epoch rather than a Besselian equinox/epoch.
Celestial Championship Series, often abbreviated CCS is a series Hearthstone tournaments, organized by Celestial.
CCS is a Blizzard sanctioned tournament, each will feature two invited pros and six qualified players, with an epic ¥5,000 prize pool.
Overview In the case of orbital elements, only a few of the classical orbital elements are affected by a switch of equinox: the longitude of the ascending node, and (to a much lesser extent) the inclination.
If another set of orbital elements are used, such as the position and velocity vectors for a particular epoch, all components can be affected by a switch of equinox.
Equinox is often confused with epoch with the difference between the two being that the equinox addresses changes in the coordinate system, while the epoch addresses changes in the position of the celestial body itself.The currently used standard equinox (and epoch) is J2000.0, which is at TT.The current standard equinox/epoch is J2000.0, which is a Julian equinox/epoch.Besselian equinoxes/epochs are calculated according to:: B = , astronomers always specify these with reference to a particular equinox.Historically used Besselian equinoxes include B1875.0, B1900.0, B1925.0 and B1950.0.The official constellation boundaries were defined in is averaged out or omitted.
