A total solar eclipse occurred on Wednesday, August 11, 1999 with an eclipse magnitude of 1.0286. 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. The path of the moon's shadow began in the Atlantic Ocean and, before noon, was traversing the southern United Kingdom, northern France, Belgium, Luxembourg, southern Germany, Austria, Slovenia, Croatia, Hungary, and northern FR Yugoslavia ( Vojvodina). The eclipse's maximum was at 11:03 UTC at 45°06′N 24°18′E / 45.1°N 24.3°E in Romania (next to the town of Ocnele Mari near Râmnicu Vâlcea); [1] [2] [3] and it continued across Bulgaria, the Black Sea, Turkey, the northeastern tip of Syria, northern Iraq, Iran, southern Pakistan and Srikakulam in India and ended in the Bay of Bengal.
It was the first total eclipse visible from Europe since 22 July 1990, and the first visible in the United Kingdom since 29 June 1927.
Because of the high population densities in areas of the path, this was one of the most-viewed total solar eclipses in human history; [4] although some areas in the path of totality (mainly in Western Europe) offered impaired visibility due to adverse weather conditions.
Some of the organized eclipse-watching parties along the path of totality set up video projectors on which people could watch the moon's shadow as it raced towards them. [5] There was substantial coverage on international TV stations of the progress of the eclipse shadow. The moon's shadow was also observed from the Russian Mir space station; during the eclipse, video from Mir was broadcast live on television.

Partial solar eclipses on July 1, 2000 and December 25, 2000 occur in the next lunar year eclipse set.
This solar eclipse is a part of Saros cycle 145, repeating every 18 years, 11 days, 8 hours, containing 77 events. The series started with a partial solar eclipse on January 4, 1639, and reached a first annular eclipse on June 6, 1891. It was a hybrid event on June 17, 1909, and total eclipses from June 29, 1927, through September 9, 2648. The series ends at member 77 as a partial eclipse on April 17, 3009. The longest eclipse will occur on June 25, 2522, with a maximum duration of totality of 7 minutes, 12 seconds. All eclipses in this series occurs at the Moon's ascending node.
