This fond contains letters, several photographs, and observations related to A. A Narayana Ayer during the year 1913-1920.

The handwritten document was an explanatory memo by John Evershed, signed in 1918. A. A. Narayana Ayyar was the 3rd Assistant of the Solar Physics Observatory, Kodaikanal, from 1913 to 1918. During that period, he also served as the 2nd Assistant of the Observatory for more than one year. The memo was about the approval of the allowance provided to A. A. Narayana Ayyar for the service as 2nd Assistant. The exact dates during which he acted as the 2nd Assistant of the Observatory are also mentioned in the document.

The order was related to granting leaves to R. Ll. Jones for 11 months and ten days. R. Ll. Jones was working as the Meteorologist at Madras and Deputy Director of the Madras Observatory.

The order is from the Government of Madras to the chairman, the Municipal Council, Kodaikanal, approving the proposal to extend its limits to the observatory buildings and as for the objection from the Director regarding the water supply, the area will be exempted from paying the water tax proviso(b) to section 84 of the Madras District Municipalities Act, 1920.

This item was a order of the extension of leave granted by His Majesty's Secretary of State for India extension of leave or permission to return to duty as advised in list dated the 13th October 1920

The award letter was regarding the order of the Indian Empire Certificate by George the Fifth of the United Kingdom of Great Britain and Ireland to John Evershed, Director of the Kodaikanal Observatory, Madras. Evershed was nominated and appointed to be the Ordinary Companion of the said Most Eminent Order of the Indian Empire.

This item was donated by Cherry Armstrong Great-Great Grand daughter of N.R.Pogson in 2006. We can see that Mr. Pogson was standing with Lucy Sylvia, An unknown Indian and Louise Camilla. Some small children were also seen in the photo seated infront, who probably be Charles Albion, Isis, and Robert Owen.

This item was the painting of Kodaikanal Observatory by an unknown artist in 1909.

Astronomer William Stephen Jacob of India made important advances in the study of Saturn. He made observations of the Sunnian system and reported his findings, which included determining the elements of Saturn's satellites and Jupiter's adjusted mass. In 1852, he and William Lassell observed the transparency of Saturn's "dusky ring" almost simultaneously. In 1861, James Breen truncated Jacob's planetary observations. The Indian government paid for the printing of his books on the Saturnian system. Important new information about Saturn and its moons was made possible by these observations and calculations. One of his best-known pieces is a sketch he made on November 15, 1852, of Saturn. Using the Madras Equatorial, this drawing was created. W. Forrest then etched it. The illustration caught the appearance of Saturn on that specific date, providing valuable insights into the planet's features and characteristics at that time.

The Observations conducted at Kavalur during the 10 March 1977 Uranus occultation of SAO158687 revealed, apart from the occultation by a satellite system known as the e ring, a decrease in the star's brightness near the moment when the planet's atmosphere could have triggered the occurrence. Since then, a theoretical explanation for the genesis of the a, ß, ?, and d rings has been put out in addition to the identities of these rings becoming firmly established. After thoroughly analysing the Kavalur photoelectric record, they provide several novel elements of Uranus' satellite ring system.
