A total solar eclipse occurred on July 28, 1851. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
Observations
The first correctly exposed photograph of the solar corona was made during the total phase of the solar eclipse of 28 July 1851, at the Royal Observatory in Königsberg, Prussia (now Kaliningrad, Russia) by Johann Julius Friedrich Berkowski, considered among the most skilled daguerreotypists in the city.[1] A small 6 cm refracting telescope was attached to the 15.8 cm Fraunhofer heliometer, and Berkowski took an 84-second exposure shortly after the beginning of totality.[2]
United Kingdom astronomers, Robert Grant and William Swan, and Austrian astronomer Karl Ludwig von Littrow observed this eclipse and determined that prominences are part of the Sun because the Moon is seen to cover and uncover them as it moves in front of the Sun.[3]
