| 释义 |
A total solar eclipse occurred on May 17, 1882. 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. Totality was visible across central Africa, the Middle East, and southeastern Asia. ObservationsA party of observers gathered in Egypt to watch the eclipse were greatly surprised when they observed a bright streak near to the Sun once totality began. By a remarkable coincidence, the eclipse had coincided with the perihelion passage of a Kreutz comet. The comet would otherwise have gone unnoticed — its sighting during the eclipse was the only observation of it. Photographs of the eclipse revealed that the comet had moved noticeably during the 1m50s eclipse, as would be expected for a comet racing past the Sun at almost 500 km/s. The comet is sometimes referred to as Tewfik, after Tewfik Pasha, the Khedive of Egypt at the time.[1] Related eclipsesSaros 126{{Solar_Saros_series_126}}Notes1. ^{{cite journal|last=Marsden|first=Brian G.|title=The sungrazing comet group|journal=The Astronomical Journal|volume=72|issue=9|pages=1170–1183|bibcode=1967AJ.....72.1170M|year=1967|doi=10.1086/110396}} References
