The '''California Environmental Resources Evaluation System''' (CERES) is a [[California Resources Agency]] program established to coordinate and provide access to a variety of [[environmental]] and [[geoinformation]] electronic data about [[California]]. The goal of CERES is to improve environmental analysis and planning by integrating natural and cultural resource information from multiple sources, then making it available on the [[World wide web]].

There is little doubt that this was the most-viewed total solar eclipse in human history, although some areas in the path of totality offered impaired visibility due to adverse weather conditions.

There was substantial coverage of the progress of the eclipse shadow across European TV stations.

* The [[BBC]] concentrated its coverage efforts on the first landfall of the shadow across the western end of [[Cornwall]] ([[St Ives, Cornwall|St Ives]] -> [[The Lizard|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.

* 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. Ironically, the clouds cleared completely just a few minutes after the eclipse was over.
* Further inland, viewing conditions were also perfect at [[Vouziers]], a country town which was gridlocked by cars from Belgian visitors. Photos from Vouziers were used on the subsequent BBC [[The Sky at Night|Sky at Night]] programme.
* The San Francisco [[Exploratorium]] featured a live webcast from a crowded town square in [[Amasya]], [[Turkey]].

Totality observed from France
The eclipse as seen from France

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 / 45.1; 24.3 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 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.

Observations

There is little doubt that this was the most-viewed total solar eclipse in human history, although some areas in the path of totality 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 of the progress of the eclipse shadow across European TV stations. 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.
  • 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. Ironically, the clouds cleared completely just a few minutes after the eclipse was over.
  • Further inland, viewing conditions were also perfect at Vouziers, a country town which was gridlocked by cars from Belgian visitors. 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.
