Kodaikanal solar observatory


The Kodaikanal solar observatory has structured a popular Astronomy art gallery within the university for the visitors. The key displays are images, reinforced by a few designs. A live solar image and the Fraunhofer array are also provided. The selection at the Observatory is one of its extremely pleased valuables. It has a selection of substantial literary works which is of historical value. The selection preserves a skeletal present literary works in Solar and Solar Terrestrial Science.

The Kodaikanal Observatory is one of the four companies of Indian Institution of Astrophysics in India. It was established in 1899 as a Solar Science Observatory .There are three spectro-heliographs which incarcerates images of the sun known as spectro-heliograms. This is the oldest one which use since 1904 to take the solar disc and prominences every day. The second one which use since 1911 which takes images of the disc everyday to help the research of the lower chromosphere. The third in use since 1960 which can catch images of the sun in any ideal color.

In Jan 1909 the Evershed impact was first recognized in this observatory. Astral information gathered by this lab is the earliest continuous sequence of its kind in Indian. Accurate exams of the equatorial electro jet are prepared here due to the unique geographic location of Kodaikanal.


Kodaikanal solar observatory also works together with the Kislovadsk Observatory in the former USSR. Solar blazes are analyzed with a Hale spectro-helioscope got in 1934 from Install Wilson Observatory. The solar structure is in regular use since 1962 which is the key ability at Kodaikanal. The 11 metre raised structure guides sunbeams into a 60 metre long subterranean route through an selection of showcases. There is a 34 cm size fixed image of the sun established and a spectrograph generating a higher quality, great dispersal, array of the natural light.


Kodaikanal solar observatory also has an 8 inches (20 cm) aperture telescope obtained from London, UK in 1866 at Madras which is used for learning comets and for visitors. The Global attractive floor and ionosphere are being analyzed at Kodaikanal since 1949 and 1952 respectively using stations surf. Kodaikanal is very close to the attractive equator which is more appropriate for the research of tropical ionosphere.
