II. Saturday, February 26th, the Moon eclipsed, invisible throughout the United States. At the above times the Moon will be in the Zenith of the following places, from which it will be very easy to determine where the Eclipse will be visible. At Beginning in Long. 130° 46' East. Gr. Obs. Latitude The latter part of the Eclipse will be visible in Europe. 9° 36′ North. 9 22 66 9 8 66 1 III. Sunday, August 7th, the Sun totally eclipsed, invisible throughout the United States and the Continent of America. h. m. Sun totally and centrally ec. on the meridian at 5 22 A. M. T. at Wash. in Lat. 26° 36' S. Long. 156° 2′ W. Mean T. at Washington. h. m. End of total darkness on the Earth at 6 27 A. in Lat. 50° 7' S. Long. 103° 9′ W. h. m. End of the general Eclipse on the Earth at 7 36 A. M. T. at Wash'ton. in Lat. 35° 13' S. Long. 111° 39′ W. This Eclipse will be visible in the greater part of New Holland and in the South Pacific Ocean, excepting a portion very near the coast of South America. The greatest north latitude attained by the path of the northern boundary of the Eclipse will be 12° 39′, on the meridian of 173° 6′ W. At the Astronomical Observatory in Paramatta, in New Holland, in Latitude 33° 48′ 49.8" S., Longitude 151° 1' 34" E., the Sun will rise eclipsed. IV. Tuesday, August 23d, the Moon partially eclipsed; visible in part to the portion of the United States east of the Mississippi, and wholly visible to the portion, west thereof. Digits eclipsed 5° 48′ on the South, Limb of the Moon. Digits eclipsed 5° 48′ on the South Limb, of the Moon. Digits eclipsed 5° 48′ on the Moon's South Limb. Digits eclipsed 5° 48′ on the Moon's South Limb. OCCULTATIONS IN 1831, Visible in Boston, and in Other Parts of the United States; the Phases of which are expressed in Mean Time for the Meridian of Boston. [Those marked with an asterisk will be visible in Europe.] OCCULTATION OF A STAR BY A PLANET. March 17th. Occultation of the Star A 1 8 by the Planet Mars. 1. The apparent Lat. and Long. of the star being deduced from the Tables of the Astronomical Society of London. Immersion Emersion 6h. 32m. 20s. A. 1.56'' North of the 2. The place of the star being deduced from the Tables in the Appendix to Dr. Pearson's Practical Astronomy. Immersion Emersion 6h. 33m. 57s. A. 0.31" South of the 0.34 S Centre. S. D. of 2.59"; apparent motion of ♂ per minute in Long. 1.532′′, in Lat. +0.010". This will probably be an occultation throughout a very large part of the United States; but it is very doubtful whether it can be observed in any place much to the westward of Boston, on account of the proximity of the Sun to the horizon. It takes place, however, at a season of the year when the twilight is about the shortest, and at a time when the star has great altitude. D's Apparent S. D. at Im. 15' 5.6''; at Em. 15′ 6.3′′.
