Resolution No.7 (1971): Magnetograms at Colaba and Alibag since 1872

Considering the great value of the century-long series of magnetograms collected since 1872 at the geomagnetic observatories of Colaba and Alibag (Bombay) to the international scientific community, IAGA recommends that arrangements be made through appropriate authorities of India

  1. for the preservation of all the original magnetograms by preparing a few microfilm copies and depositing them in Indian and International World Data Centers and
  2. for appropriate scaling of the records of the period 1872-1924.
