INTRODUCTION.
In the following pages, lists of bright stars and planets for each of the
months December, 1907, January, February, and March, 1908, have been
arranged for the convenience of navigators. The monthly lists contain the
fixed stars given in the list on page 5, together with the four planets Venus,
Mars, Jupiter, and Saturn, excepting that stars and planets within 30° of the
sun have been omitted.
In the American Ephemeris for 1908, pages 324 to 399, inclusive, there
are given the apparent places for every ten days of nearly 40O stars, prima-
rily for the use of astronomers. To the navigator only about 40 of the
brighter stars are available. By arranging a list limited approximately to
stars which may be observed with the sextant when the sea horizon is visible
in twilight or moonlight, the selection and identification of the stars is made
easier.
The quantities given in the columns headed “Daily Variation " are to be
multiplied by the number of intervening days and added algebraically for
dates following the 15th of the month, and subtracted algebraically for dates
preceding the 15th of the month. In case of the planets, the “Daily Varia-
tion ” should not be used when accurate positions are desired. The references
in the footnotes give the page in the American Ephemeris and Nautical
Almanac where the exact position of the planet for the time of observation
may be interpolated from its daily ephemeris. .
The chart attached is intended to aid in the identification of the stars
on the monthly lists and has been constructed by means of a modification
of Mercator's Projection. In addition to the stars on the lists, a number of
fainter stars, needed to give the outlines of the principal constellations, are
shown as are also the paths of the sun and moon for the year 1908. In order
to avoid complication, all names and dates, as well as the paths of the
planets, have been omitted from the chart. The position of the sun, moon,
or a planet, for any given time can be found in the Ephemeris and laid
down on the chart when necessary, and the names of the stars and constel-
lations can be found by taking the approximate right ascensions and decli-
nations off the chart and referring to the star lists.
