The third contact

The most important thing which is absolutely necessary for total solar eclipse observing is good luck. A single cloud on a clear sky may ruin everything. It was twice truthful for 2002 eclipse in South Africa. December is, from the point of weather, a very bad month. Many expeditions were unsuccessful. The Slovak expedition organized by Vojtech Rušin had really an enormous luck. They took 21 images in unstable weather and only the last one was significantly influenced by clouds. This last picture I excluded from processing at first (see this picture). This last picture shows Baily's beads at the third contact and coming clouds. It is not of big scientific value but it is nice and therefore I used this picture to create picture of the 2002 total eclipse which you can see on this page.
