Annamalainagar Observatory was started in October 1957 as a part of India's participation in the International Geophysical Year (IGY) program. It is situated in the Annamalai University campus. This site is about 10 km away from the east coast of India and it is coming under the proximity to the periphery of Equatorial Electrojet belt. This observatory was closed down in December 1993. But observations from the Pondicherry observatory since 1994, maintain the continuity for the latitude.
