Annular Solar Eclipse in Madrid

October 3rd, 2005

We were a small group of 4 Danes who travelled to Madrid to see the annular solar eclipse. After having checked a number of possible observation sites we finally chose the western side of the large lake in the Retiro Park as our observation site. Several hundred other eclipse observers had made the same choice but there was place for everybody.

We saw the event on a perfect blue sky. I wish we've had that weather in South Africa!

I had put Danish flags on my telescope - a birding scope with Baader solar filter. Many people passing by asked: "You're from Norway?"

Exposure: f/11, 1/1000 sec, 400 ASA, Baader solar filter.

Due to the rotation of the Earth, the Sun seems to move about 30' (arc minutes) across the sky every two minutes. The angular diameter of the Sun is a little larger - about 32' - that's why the images are overlapping.

While definitely not as spectacular as a total eclipse, it was an exciting and fascinating experience - well worth the trip to Spain.
