Soon extinguished sun – New Technology

A few minutes to eleven today’s solar eclipse over Sweden’s deepest. If the weather is gracious will be able to follow the eclipse on the web from at half past nine

Astronomers at the Ångström Laboratory has assembled a small eight-inch telescope with shade outside the university’s major Westerlund Telescope. The telescope will be filming eclipse and put out the natural phenomenon on the Web from half past nine in the day.

A solar eclipse occurs when the moon places itself in a straight line between the Earth and the sun. A total solar eclipse occurs when the Moon covers the entire solar disk. They just get the experience that resides on Svalbard or the Faroe Islands.

In Sweden, we only experience a partial eclipse, the greatest, the longer north and west you are. In Kiruna, there is a good chance for a fine experience. Partly see the weather forecast good, partly covered almost the entire solar disk.

The moon begins to cast its shadow over Sweden early on Friday morning, but cover only a portion of the surface at a time. The sun will be darkened at most minutes around the clock 11. Then slide the moon on the disc of the sun and the light will gradually withdrawn.

All this must be seen on the web in the morning by special instrument which astronomers at the Ångström Laboratory mounted on the roof of the Department of Physics and Astronomy – provided the weather is clear.

– Yes, it is, unfortunately. If it is cloudy, it will not appear at all. It just gets black because of the sharp filters that we use to weaken the light from the sun, says Ola Karlsson, PhD and astronomer at the Ångström Laboratory.

It is he who initiated the webcast. The idea emerged when it planned a tour of the solar eclipse on the big science festival that the University organizes for schoolchildren in Uppsala for three days.

– It was a colleague who suggested that we could simultaneously posting pictures online, says Ola Karlsson to new technologies.

A solar eclipse of the dignity that we get the chance to consider from Sweden on Friday arouse interest among both the general public, hobby astronomers, professional astronomers and scientists.

Despite that the moon obscures much of the sun’s light is still too hard to look directly at no great eye protection, type welding glasses or specially designed solförmörkelseglasögon. To that at the great eclipse in the 1950s using blackened glass is not recommended today. There are better protected.

The safest is, however, an indirect picture – that with a mirror facing the sun cast a reflection of the sun on a wall ten feet away. Or to use an ordinary pair of binoculars and project the image of the eclipse on a piece of paper behind the telescope. Then you get a picture of the eclipse without risking the eyes.

– But you must not look through the binoculars, says Ola Karlsson.

However, you can use your mobile camera.

– You can put a” look “filter in front of the camera, take a picture and look at the picture instead. It is absolutely safe – for the eye, anyway, he said.
