The European satellite organisation Eumetsat will update pictures every 10 minutes of the Moon's shadow as it rushes across the globe. Meanwhile, the European Space Agency has brought together a wide range of material - including some of the experiments scientists hope to carry out - on their own web site ESA Eclipse99.

Although the eclipse will mainly be seen in Europe, the US space agency NASA has constructed some excellent teaching resources for the web. They have a live webcast and press releases on the eclipse and on some experiments scientists hope to carry out during the eclipse. However, their best page is an extensive list of every expedition, web page and web-broadcasting site on the internet connected with the event.

Both the two main UK news organisations also have eclipse webs sites, with ITN having more colourful graphics and the BBC more background information. The official UK government site can be found at Eclipse99.
