Definition
The celestial equivalent of latitude, tabulated in the Nautical Almanac for each hour of GMT with a d correction for the hourly rate of change. The sun's declination swings between about 23.4 degrees north at the June solstice and 23.4 degrees south at the December solstice, crossing zero at the equinoxes. Stars have effectively fixed declinations over a year, so they are listed once per almanac page rather than hourly.
