About this observatory

On Colaba Island in Mumbai, India, the Colaba Observatory has been a scientific fixture for nearly two centuries, tracking everything from stellar transits to the Earth's magnetic field.

About Colaba Observatory

Also known as the Bombay Observatory, it was founded in 1826 by the East India Company as an astronomical, timekeeping, geomagnetic and meteorological station.

History

Astronomer Arthur Bedford Orlebar began systematic geomagnetism and meteorological recordings there in 1841, and equipment supplied by Francis Ronalds of Kew Observatory, including atmospheric electricity apparatus and photo-recording instruments, was installed in 1846 and 1867. Continuous magnetic records began in 1871, forming one of the world's most complete geomagnetic datasets, later verified by researcher Pierre Noel Mayaud in 1973. In 1900 the observatory's magnetic operations were moved to Alibag to escape interference from a planned electric tram system, and in 1971 the institution became the autonomous Indian Institute of Geomagnetism. The original 1826 building still stands as the institute's Mumbai headquarters, with the institute now operating ten magnetic observatories across India.

Location & getting there

The observatory is located on Colaba Island in south Mumbai, India, in the heart of one of Asia's largest cities.
