The Indian Institute of Geomagnetism (IIG) in 1982, 1986, and 1996, operated a Proton Precession Magnetometer (PPM) at its Antarctic stations Dakshin Gangotri/Maitri (located at ∼70°S, ∼12°E). Comparison of the average quiet-time value of total intensity F for these years with values of F obtained a...
