Answer:

Quoting shrik

1. Pierre Janssen
2. The clear yellow line is at 587.49nm in the spectrum
3. Guntur :p

Janssen noticed this wavelength while watching a total solar ecipse in Guntur, which led him to discover Helium.

    Pierre Jansen discovered Helium using spectroscopic techniques, during the great solar eclipse of 1868 – he did this at the Andhra town of Guntur, munching on red chillies.

    Lockyer did similar stuff later in the year, but not in Guntur :)

    Guntur is situated at a crucial longitude for synoptic coverage of solar phenomena. It was on August 18, 1868 in the tobacco fields of Guntur that the French astronomer, Pierre-Jules-Cisar Janssen (1824-1907), stumbled upon a yellow line in the solar spectrum while observing a solar eclipse. He christened it `Heliose’, from the Greek word helios, which means sun.


  6. Helium

    Pierre Janssen
    Helium – Helium was first detected in the Sun due to its characteristic spectral lines
    Pierre Janssen first discovered helium while observing a solar eclipse while at Guntur
