During the 19th century, there were 249 lunar eclipses of which 90 were penumbral, 97 were partial and 62 were total. Of the total eclipses, 51 were central, in the sense that the Moon passed through the very center (axis) of the Earth's shadow. In the 19th century, the greatest number of eclipses in one year was five, in 1879, though the years 1803, 1806, 1810, 1814, 1821, 1828, 1832, 1839, 1843, 1846, 1850, 1861, 1868, 1886, 1890, and 1897 had four eclipses each. One month, May 1817, featured two lunar eclipses, on May 1 and May 30. The predictions given here are by Fred Espenak of NASA's Goddard Space Flight Center.
