  • P.R. Chidambara Ayyar joined as an Assistant at the Solar Physics Observatory, Kodaikanal on April 20th 1920. He was a graduate from the Madras University and had put in six years and nine months in the meteorological department of government of India as a permanent first assistant before joining Kodaikanal observatory. In 1918 Mr. G. Nagaraja Ayyar who was a 2nd Assistant at Kodaikanal Observatory fell ill with a severe attack of influenza and subsequently died, his post became vacant and Chidambara Ayyar was appointed as a second assistant.

Chidambara Ayyar was a well recognized scientist. He worked in solar physics and wrote a paper on the relationship between the heliographic latitude of the earth and prominence numbers east and west of the Sun axis during the years 1904-1920 (KOB-67).
