On August 11, 1999, a total eclipse of the Sun, with an eclipse magnitude of 1.029, occurred.
The path of the moon's shadow began in the Atlantic Ocean and, before noon, was traversing Cornwall, Devon, northern France, Luxembourg, southern Germany, Austria, Hungary, and northern Serbia. Its maximum was at 11:03 UTC at 45°06′N 24°18′E / 45.1°N 24.3°E in Romania (next to a town called Ocnele Mari near Râmnicu Vâlcea); and it continued across Bulgaria, the Black Sea, Turkey, Iran, southern Pakistan and Srikakulam in India and ended in the Bay of Bengal.
It was the first total eclipse visible from Europe since July 22, 1990, and the first visible in the United Kingdom since June 29, 1927.

[edit] Observations
Because of the high density populated in the areas of the path (see just on top), there is only little doubt that this was the most-viewed total solar eclipse in all human history; although some areas in the path of totality (mainly in Western-Europe) offered impaired visibility due to adverse weather conditions.
Some of the organised eclipse-watching parties along the path of totality set up video projectors on which people could watch the shadow as it raced towards them[1]. There was substantial coverage on European 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.
- The BBC concentrated its coverage efforts on the first landfall of the shadow across the western end of Cornwall (St Ives -> Lizard), which was packed with an extraordinary number of British visitors. The seasoned veteran eclipse-watcher, Patrick Moore, was brought in to head a live programme, but was unfortunate to be clouded out. BBC One also Produced a Special version of their Balloon Idents for the event.
- Some of the best viewing conditions were to be had in mid-Channel, where ferries were halted in calm conditions to obtain an excellent view.
- A gathering of several thousand people at the airport in Soissons, France, which was on the path of totality, were denied all but a few fleeting glimpses of the eclipse through the overcast sky. Frustratingly, the clouds cleared completely just a few minutes after the eclipse was over.
- Further inland, viewing conditions were also perfect at Vouziers, a French country town which was gridlocked by Belgian cars from day-visitors. The patchy cloud covering cleared a short time before the shadow arrived. Some photos from Vouziers were used on the subsequent BBC Sky at Night programme.
- The San Francisco Exploratorium featured a live webcast from a crowded town square in Amasya, Turkey.
- Doordarshan, the national TV channel in India broadcast a live coverage from Srikakulam, hosted by the renowned TV personality, Mona Bhattacharya.
