Solar Eclipse - when the day gets dark

Solar Eclipse - when the day gets dark: solar

Ricc - I blog for you

A solar eclipse is a unique experience and fascinates again and again. Maybe because it is rare. At least if we limit ourselves to Germany and especially to a total eclipse. Also, the following on March 20 is a total eclipse, but with us only with a maximum of 82% visible. But already that could be enough to cause a bit of chaos. After all, feeding solar energy today is a complicated affair. Partly now already warned of power outages.

My last witnessed solar eclipse on 11.8.1999 was quite unspectacular. Even though, unlike many other regions, I had quite good weather and a good view. The total solar eclipse of '99 was turned into a media highlight and caused mass travel to big showcases and congestion in many regions. At that time I was still working as a chipper and with forge in the company, we could look at the solar eclipse through welder discs - even if these unfortunately offer no real protection.

So we are already at the most important point:

How should we look at a solar eclipse?

Sun protection film

The only right way is to buy a ready-made sunshade. Here one should rely on sales of opticians and solariums. Such glasses have the CE mark and protect the eyes from dangerous radiation. Often you hear that dark sunglasses or tinted transparencies, unexposed movies and CD's are enough. That is not true and is too dangerous for our eyes.

A pair of sunglasses does not provide adequate protection!

If you really want to build your own eclipse sunglasses, you should use certified sun protection film. Only she guarantees optimal protection. This film is also suitable for binoculars and cameras.

Build a pinhole camera yourself

Another possibility is the pinhole camera. Since the light only passes through a very small opening, it is much weaker than in a normal camera and can therefore be considered without hesitation. Construction instructions can be found here:

What is a solar eclipse?

Structure explaining the solar eclipse

In principle, this is a fairly simple thing that can well demonstrate to inquisitive children on a small experiment. All you need is a lamp and two balls of different size (optimally a globe). These are arranged one after the other and represent - lamp = sun, small ball = moon and big ball = earth. If the moon aka "small ball" is held between the sun and the earth, it casts a shadow on the earth. In this shadow, the sun "hides" behind the moon and there is a solar eclipse.

The shadow also makes it easy to see why a solar eclipse can never be seen anywhere on earth.

When will the next solar eclipse be seen?

We should definitely take the time and watch the eclipse on 20.3.2015. Because at least in Germany after a long break is announced.

  • March 20, 2015 total solar eclipse in Germany between 75% and 83% visible
  • 3rd Sept. 2081 Total solar eclipse in Germany is 100% visible
  • Oct. 7, 2135 Total solar eclipse in Germany is 100% visible

Eyes shut and go for it. ?
