NGRI studying earth’s magnetic fields

Many facilities inaugurated at Choutuppal Intermagnet Geomagnetic Observatory

Do you know that the earth’s magnetic compass keeps changing? Or, that it takes up to 48 hours for the solar storms to hit the earth despite travelling thousands of kilometre a second and potentially disturb the telecommunication systems? Changes in the geomagnetic fields could affect the GPS systems too based on which the modern travel is dependent on. These fascinating observations as also the underground plate movements along with quakes are taken note of on a continuous basis in the 100 acres verdant off-site campus of CSIR-National Geophysical Research Institute (NGRI) where Director General Dr. Shekhar C. Mande inaugurated several new facilities at the Intermagnet Geomagnetic Observatory at Choutuppal, 65 km away from the twin cities. A ‘Component Fluxgate Magnetometer’ and ‘Overhauser total field magnetometer’ to continuously measures the earth's magnetic field at an interval of one second and send the data to ‘Intermagnet’ - the global data repository of geomagnetic observatories, were among those unveiled.
