Note. To make use of the above table in connection with the chart of the heavens proceed as follows: Suppose the position of Venus for May 11 is desired, right ascension for that date is III1⁄2 hours. Locate that point on the outer margin of the chart and upon connecting this point, by a straight edge,

as a ruler or envelope edge, with the north star, the line will cross the "ecliptic circle" at a point nearly midway between the Pleiades and Hyades, where Venus may be found at that time; or close to Regulus in the Sickle of Leo about the last of July.

POSITIONS OF THE PLANETS FOR THE SUNDAYS OF THE YEAR.

CHART OF THE TOTAL ECLIPSE OF THE SUN JAN. 24, 1925.

Note-The lower or south portions of the ines .6 and 8 should have been interrupted

instead of solid, but space made the addition of the usual loop lines impracticable.

TOTAL ECLIPSE OF SUN JAN. 24. There will be four eclipses this year, two each of the sun and moon, as follows:

See

I. Total of the sun Jan. 24. See the chart of this eclipse on the opposite page, by the use of which persons knowing their approximate location in any state can, at a glance, know all the details of the eclipse for such location closely enough for all the practical purposes. Examples: At Pittsburgh, Pa.. it will begin at 7:56 a. m.; middle or greatest eclipse 9:04 a. m., ends 10:18 a. m.; size at middle or greatest eclipse .94 on the sun's northern limb. or a trifle larger than it will be at Chicago; see figures. At Auburn, Me.. begins 8:06 a. m.; middle 9:20 a. m., ends 10:40 a. m.; size .95 or a little smaller than at Boston and on the southern limb. figure. At Eau Claire, Wis., sun rises with eclipse on and increasing, being between the lines A and B figure 4 and will reach the size shown for Chicago or 95 at 9 a. m. and end at 10:10 a. m. eastern standard time. Subtract one hour for central standard time. At Watertown, S. D., the sun will rise with eclipse on also, but decreasing in size, being between the lines B and C. figure 4: size at rising 8 and will end at 10:05 a. m. eastern standard time. Subtract one hour for central standard time. At Ithaca, N. Y., total, the partial phase beginning at 8 a. m.: middle at 9:13 a. m., ends 10:26 a. m. Duration of totality 1.8 minutes, which will be about the same throughout the belt of totality near its center, decreasing each way from the central line to the margins.

These illustrations include for every possible location conditions as shown by the following cuts: No. 1 shows the beginning lines at 5 minute intervals. West of the line A the sun will rise more or less eclipsed to the line C in figures 3 and 4. No. 2 shows the times of greatest eclipse, which occurs at sunrise on the line B. No. 3 shows the ending lines at 5 minute intervals, no part of the eclipse being visible west of the line C. No. 4 shows the size in tenths (1:00 being total), south of which belt the eclipse will be

.82

on the sun's northern limb and north of it upon the southern limb of the sun. Between lines A and C the size at sunrise is indicated for every 2 at the bottom of the perpendicular lines. But between A and B it will be increasing and between B and C decreasing at the rising of the sun, and the maximum is shown by the lines at right angles to these, terminating at line B, on which the greatest eclipse will be at sunrise.

The sun will be totally eclipsed Jan. 24 as the moon cuts in between the earth and sun. The total phase will last but about two minutes and will be best observed in New York state (see under eclipses). The path of totality will be only about 100 miles at its western end and 140 in eastern

As he rapidly approaches the sun he will be very dim in the sun Sept. 13, and invisible for a considerAugust-September, being in conjunction with able period before and after that date. At this time he will pass to the west of the sun and become a morning star, and will not be again attractive until December, when, on the 15th, he will pass 2 degrees south of Saturn while in the Square of Libra. He will not be as bright at the end of the year as at its beginning.

No signals from Mars were detected at the time of his near approach. Aug. 23, 1924, as hoped for, but there is still plenty of time, as the distance between us will increase only slowly.
