We give below, in tabular form, a list of the principal total eclipses during the 19th and 20th centuries, omitting a few visible only in the extreme polar regions, and some others of which the duration is very short. The first column gives the civil date of the point on the earth's surface at which the eclipse is central at noon. The next two columns give the position of this point to the nearest degree. The fourth column shows the Greenwich astronomical time of conjunction in longitude. The next column gives the duration of the total phase at the noon-point; this is sometimes 0.1' less than the absolutely greatest duration at any point. Next is given the node near which the eclipse occurs; and then the number in the Saros. Corresponding eclipses at intervals of 18 y. 11 d. have the same number, and occur near the same node of the noon, which is indicated in the next column. +----------------+--------------+---------------+---------+------+-------+------------------------------------------------------------+ | | Point where |Greenwich M.T. |Duration | | | | | Date at | Central at |of conjunction | of | | | | | Noon-Point. | Noon. | in Longitude. |Totality.| Node |Series.| Regions Swept by Shadow. | | +------+-------+---------------+---------+ | | | | | Lat. | Long. | d. h. m. | m. | | | | +----------------+------+-------+---------------+---------+------+-------+------------------------------------------------------------+ | 1803, Feb. 21 | 11 S.| 136 W.| 21 9 20 | 4.2 | Asc. | 1 | Pacific Ocean, Mexico. | | 1804, Aug. 5 | 38 S.| 66 W.| 5 4 6 | 1.2 | Desc.| 2 | Pacific Ocean, Chile, Argentina. | | 1806, June 16 | 42 N.| 66 W.| 16 4 22 | 4.6 | Desc.| 3 | New England, Atlantic, Africa. | | 1807, Nov. 29 | 11 N.| 2 E.| 28 23 48 | 1.4 | Asc. | 4 | Central Africa, Areolia. | | 1810, April 4 | 12 N.| 154 E.| 3 13 41 | Ann. | Desc.| 5 | Pacific Ocean, Borneo. | | 1811, Mar, 24 | 39 S.| 26 W.| 24 2 19 | 3.4 | Desc.| 6 | South Atlantic to and across South Africa. | | 1814, July 17 | 31 N.| 84 E.| 16 18 33 | 6.6 | Asc. | 7 | Africa, Central Asia, China. | | 1815, July 6 | 88 N.| 175 W.| 6 11 52 | 3.2 | Asc. | 8 | Polar Regions, Western Siberia. | | 1816, Nov.
