The process of finding the time will also lead to finding the Greenwich Hour Angle and declination of the moon at the time of interest.
22.
Using an object's right ascension and the local sidereal time it is possible to determine the time of its culmination . ( See hour angle ).
23.
Officials concerned that night-fishing in Mono County is unsafe have won a reversal of the recent action permitting 24-hour angling in the popular Eastern Sierra destination.
24.
Is the local hour angle simply the observer's degrees of longtitude ? ( You talkin'to me ? ), 22 : 42, 23 February 2010 ( UTC)
25.
More generally, in the particular case of two planets, it means that they merely have the same right ascension ( and hence the same hour angle ).
26.
To calculate the azimuth of the sun or a star given its declination and hour angle at our location, we modify the formula for a spherical earth.
27.
For purposes of identification, the positions of navigational stars & mdash; expressed as declination and sidereal hour angle & mdash; are often rounded to the nearest degree.
28.
Polar mounts work in a similar way to astronomical equatorial mounts in that they point at objects at fixed hour angles that follow the astronomical right ascension axis.
29.
On page 44 ( chapter 8 ) he defines ( along with the observer's latitude ) " H = the local hour angle, measured westward from the South ".
30.
Replace " ? " 2 with declination and longitude difference with hour angle, and change the sign ( since the hour angle is positive westward instead of east ).
