Anomalies in transient geomagnetic variations have been previously studied using data from five permanent observatories in the peninsular India. The results from the three observatories falling under the equatorial electrojet showed the presence of a strong current concentration between India and Sri Lanka Island. The currents seem to flow at the depth of the crust or upper mantle. These findings have been confirmed hereby by collecting data from an array of magnetometers. We associate the channelling to the presence of a geological conductor between India and Sri Lanka Island.
