Solar eclipse of February 11, 1804

A hybrid (annular/total) solar eclipse occurred on February 11, 1804. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An hybrid solar eclipse shifts between a total and annular eclipse. At certain points on the surface of Earth it appears as a total eclipse, whereas at other points it appears as annular. Hybrid eclipses are comparatively rare. This eclipse is a hybrid event, a narrow total eclipse, and beginning and ending as an annular eclipse. The greatest eclipse was in the Sahara Desert in modern-day Algeria at 26.7 N, 4.5 W at 11:16:33 UTC, in that portion it shown as a total eclipse, the remainder was as an annular.
