Hour Angle

Noun

1. The angular distance along the celestial equator from the observer's meridian to the hour circle of a given celestial body.

DomainDefinitions

Aerospace

Angular distance west of a celestial meridian or hour circle; the arc of the celestial equator, or the angle at the celestial pole, between the upper branch of a celestial meridian or hour circle and the hour circle of a celestial body or the vernal equinox, measured westward through 360 degrees.Hour angle is usually further designated as local, Greenwich, or sidereal as the origin of measurement is the local or Greenwich celestial meridian or the hour circle of the vernal equinox. See meridian angle. (references)

Space

The angular distance of a celestial object measured westward along the celestial equator from the zenith crossing. In effect, HA represents the RA for a particular location and time of day. (references)

Specialty Definition: Hour angle

(From Wikipedia, the free Encyclopedia)

In astronomy, an object's hour angle (HA) is defined as the difference between the current local sidereal time (LST) and the right ascension (RA) of the object:

HAobject = LST - RAobject

Thus, the object's hour angle indicates how much sidereal time has passed since the object was on the local meridian. It is also the angular distance between the object and the meridian, measured in hours (1 hour = 15 degrees). For example, if an object has an hour angle of 2.5 hours, it transited across the local meridian 2.5 hours ago, and is currently 37.5 degrees west of the meridian. Negative hour angles indicate the time until the next transit across the local meridian. Of course, an hour angle of zero means the object is currently on the local meridian.
