ECLIPSES OF THE SUN. FROM 1822 TO 1900. A Catalogue of all the Eclipses of the Sun, between 1822 and 1900, Visible in the City of Boston, in Lat. 42° 20′ 58′′ North, and Long. 71° 4′ 9′′ West from Greenwich, in Mean Time for the Meridian of Boston, reckoned Astronomically. This catalogue was carefully calculated, in the years 1822 and 1823, by the editor of this part of the Almanac; but as the lunar tables used are not now considered the most accurate, the phases of the eclipses are to be considered near approximations only; excepting, however, the eclipses of 1824, '25, '32, '54, and '75, which have since been recomputed. The Semidiameters of the Sun and Moon were diminished according to the theory of Duséjour. [Those marked with an asterisk will probably be visible in some part of Europe.] 1824. June 26th. Beginning 7h. 27m. 5s. 7 36 Digits eclipsed at Sunset 1° 8'. The beginning of this eclipse was observed from a hill in the vicinity of Boston, at 7h. 27m. 18s. This eclipse was the first return of the eclipse of June 16th, 1806, when the Sun was totally obscured at Boston, about five minutes. 1825. December 9th. Beginning 3h. 53m. 13s. 4 23 Digits eclipsed at Sunset 4° 50'. A very small cloud passed over the Sun exactly at the time of the beginning of the eclipse, and prevented the same from being observed; but at 35 seconds after the computed time of the beginning, the part eclipsed was very perceptible. This eclipse was total in the south extremity of Florida. 1831. February 11th & 12th. See pages 5-26. 21 0 6 Digits eclipsed 4° 49′ on Sun's South Limb. In the city of St. Jago, in the S. E. extremity of Cuba, in Lat. 19° 57′ N. Long. 76° 5' W., the eclipse will be total, and very nearly central. Beginning of Total Darkness Nearest Approach of Centres 19 22 End of Total Darkness 19h. 20m. 33s. 41 19 24 48 The city of Kingston in Jamaica, in Lat. 18° 1' N., Long. 76° 51′ W., is situate south of the southern boundary of the total eclipse. The Ap. o at Kingston (M. T. at K.) will take place at 19h. 18m. 43s. 19 18 15 Greatest Obscuration (11° 44' on Sun's North Limb) The path of the southern boundary of the total eclipse will probably pass over the N. W. extremity of Jamaica, near Montego Bay. At the southern extremity of the United States, the obscuration will be about eleven digits, on the South Limb. This eclipse, taking place at a time when the Sun is nearly at his greatest possible distance, and the Moon at nearly her least possible distance, from the Earth, the width of the Moon's shadow on the Earth will be much greater than usual; so that where the sun is centrally eclipsed near the nonagesimal and the zenith (in Africa), the duration of total darkness will rather exceed six minutes. A fuller account of this eclipse will be given in our Almanac for 1832. Digits eclipsed 10° 31′ on Sun's South Limb. The Sun will be totally eclipsed in South Carolina and Georgia. This eclipse will be annular in the West Indies, in the north part of England and Ireland, in the south part of Scotland, and the north part of Germany and Denmark. Digits eclipsed 10° 52' on Sun's South Limb; at the greatest obscuration, Moon's Lower Limb, 38" South. This eclipse will be nearly central at Washington, where the ring will last about six minutes. The Sun will be annularly eclipsed in three fifths of the States of the Union, the Moon at the time of the eclipse being at her greatest possible distance from the Earth. Digits eclipsed at Sunset 2° 6' ; at Greatest Obscuration 2° 9' on Sun's North Limb. The Sun will not be eclipsed in the Southern States, or centrally in any place. Digits eclipsed at sunrise 4° 26'. 16h. 55m. Os. 17 18 10 This is the third return of the eclipse of April 2d, 1791, which was annu.ar in Boston. Digits eclipsed 6° 43′ on Sun's South Limb. United States south of Part eclipsed 0° 10' on Sun's North Limb. The Sun will not be eclipsed, in any part of the Connecticut, or centrally in any part of the Earth. Beginning *1851. July 27th. 19h. 48m. 24s. Greatest Obscuration 20 38 44 End of the Eclipse Digits eclipsed 11° 20'. D's Ap. Lat. at Nearest Ap. 50" North. This Eclipse will probably be annular in Boston, and in some part of New York, Vermont, Massachusetts, New Hampshire, and Maine. Digits eclipsed at Sunrise 1° 39'; at Greatest Obs. 5° 31' on Sun's South The eclipse will not extend to the Southern States, and will not be Digits eclipsed 6° 12′ on Sun's North Limb. South Limb. Digits eclipsed at Sunrise 1° 51'; at Greatest Obscuration 4° 22′ on Sun's Digits eclipsed 8° 18′ on Sun's South Limb. This eclipse will be annular in the States of North and South Carolina; at Charleston the ring will last 6 minutes. This is the third return of the Eclipse of September, 1811, which was annular in Virginia. Part eclipsed 0° 31′ on Sun's North Limb. South of Connecticut there will be no eclipse, and no central eclipse in any part of the Earth. Digits eclipsed 10° 14' on Sun's South Limb. This eclipse will be total in North Carolina and Virginia. *1873. May 25th. The Sun and Moon will be in contact at Sunrise; but the Sun will be eclipsed to places at a greater distance from the Equator, and in less longitude from Greenwich. Ap. Lat. of the Moon at N. Ap. 29" North. Digits eclipsed at Sunrise 7° 14′ at N. Ap. 11° 25′ This eclipse will be annular in Boston and in some part of Maine, New Hampshire, Massachusetts, and Vermont. |
