TABLE VIII.

Right Ascensions and Declinations of some of the principal Fixed Stars, adapted to the beginning of the Year 1830, with their Annual Variations.

NOTE.-If the places of these stars are wanted for any time before the beginning of the year 1830, multiply the annual variation, in right ascension, by the number of years before 1830, and subtract the product from the right ascension standing in the table; but the product of the annual variation in declination by the number of years before 1830 must be added to, or subtracted from the declination, according as the sign or is marked in the Table; but for any years after 1830, the annual variation in 'right ascension, multiplied by the number of years after 1830, must be added to the right ascension in the Table, and the annual variation in declination, multiplied by the number of years after 1830, must be either added to, or subtracted from the declination, according to the signs in the Table. The Annual Variation is set down for seconds and decimals of a second. An asterisk is prefixed to the stars whose distances from the moon are given in the Nautical Almanac. When very great accuracy is required, the corrections found in Tables XLII. and XLIII., for aberration and nutation, are to be applied to the numbers deduced from Table VIII.; but these corrections are generally not of much importance in nautical calculations. The corrected values are, however, given in the Nautical Almanac for 100 of the bright stars of this catalogue for every ten days in the year, and these values are always to be preferred.

A TABLE showing the Time of the Sun's Setting, when the Latitude and Declination are of the same Name, and the Time of its Rising, when the Latitude and Declination are of different Names.
