Colaba Geomagnetic Research Laboratory (CGRL) Colaba

The first magnetic observations in India were started at Madras in 1822, followed by the recordings at Simla (1841), Trivandrum (1841) and Colaba (1841). Among these, only Colaba observatory continued uninterrupted since 1841. The combined observations at Colaba and Alibag observatories provide the longest series (nearly 175 years) of magnetic field data.
