Mercury is brightest when at an elongation of about 22° 19′, which occurs about three days before its greatest elongation east, and three days after its greatest elongation west, and is always between the greatest elongation and superior conjunction. Venus is brightest between inferior conjunction and greatest elongation, and when its elongation is about 39° 44′.
ECLIPSES FOR 1869.
There will be four Eclipses this year, two of the Sun and two of the Moon, as follows:
I. A partial eclipse of the Moon, January 27th, in the evening, visible. Size, 0.458 of the diameter, or 5.496 digits, on the northern limb. See table of Lunar Eclipse, page 14, for the time.
The first contact occurs at a point 50° from the north point towards the east, and the last contact 31° from the north point towards the west. The north point of the Moon is determined by an imaginary line drawn from the Moon's centre toward the north pole, or North Star, and not toward the north point of the horizon. When the Moon is at A the Eclipse is largest and on the northern limb.
II. An annular eclipse of the Sun, February 11th, invisible in North America. Visible in the southern part of South America, south of 20° latitude, and in the southern part of Africa.
This Eclipse will be partial in the lower part of South America, and Southern Africa. The line of the Central Eclipse travels in the Ocean, and ends on the coast of Madagascar. The Eclipse begins in Lat. 35° 39' S., Lon. 3° 12.3′ W., and ends in Lat. 9° 47.4 S., Lon. 256° 27.3′ W.
total at noon in Alaska, Lat. 61° 46.9 N., Lon. 68° 4.6′ West. The line of the total eclipse now runs south-easterly, grazing the coast near Sitka, thence running off into British America, and entering the United States near the origin of Milk River, Lon. 30° W. Thence through the South-west corner of Minnesota, and diagonally through Iowa, crossing the Mississippi River near Burlington, Iowa; thence through Illinois, just north of Springfield, and crossing the Ohio River near Louisville, Ky. Thence through the south-west corner of West Virginia, and through North Carolina, just south of Raleigh, and thence to Newbern, and entering the Atlantic, just north of Beaufort, N. C., and ending at sun-set, in the ocean, in Lat. 31° 15.2 N., and Lon. 9° 36.6′ East.
In all the dark part of the engraving the Eclipse will be visible and partial, except along the heavy black line, where it will be total.
Along the line described above, the eclipse will be total, and at all other places in the United States it will be partial. The partial eclipse ends on the Earth at sun-set, in Lat. 14° 48′ 54" N., Lon. 13° 10′ W., being near the City of Guatemala. Along the Atlantic coast in the United States, the eclipse ends at about sun-set. For the times of the phases of this eclipse, see the following table. For its general outline, see the engraving.
This eclipse occurred last in 1851, July 28th, and the total phase was visible in the arctic regions of America, and in Sweden, Norway and Russia.
