The first solar eclipse of 2011 was on the 4th January.
Helium was first discovered in the spectrum of the sun before it was found on Earth. Scientists noted a yellow line in the solar spectrum during a solar eclipse in 1868, which was later determined to be due to the presence of helium.

As soon as there was a solar system.

The spectral line for helium was first discovered by a French astronomer working in India during a solar eclipse. An English astronomer determine that this spectral line was due to a previously unknown element. An Italian physicist first detected helium on Earth. A Scottish chemist, was the first to isolate helium on Earth. So where was helium discovered? Depending on how you define "discovery" it was discovered in India, France, England, Italy or Scotland.
