Colaba Observatory
Coordinates: 18°38′44″N 72°52′11″E / 18.645513°N 72.869611°E Colaba Observatory was an astronomical, timekeeping, geomagnetic and meteorological observatory located on the Island of Colaba, Mumbai (Bombay), India.
The Colaba Observatory is located in Bombay and was built in 1826 by the East India Company for astronomical observations and time-keeping, with the purpose to provide support to British and other shipping which used the port of Bombay. The 165-year-old building served as office space for the Indian Institute of Geomagnetism. The recording of geomagnetism and meteorological observations was started at the observatory in 1841 by Arthur Bedford Orlebar, who was then Professor of Astronomy at Bombay’s Elphinstone College. Magnetic measurements between the years of 1841 and 1845 were intermittent; following 1845 they became bi-hourly, then hourly.
