Magnetic Observatory Nagpur

For understanding the complexities of equatorial electrojet feature, a control station outside its influence but having practically similar variations caused by distant (magnetospheric) currents become crucial. Magnetic measurements at Alibag have been serving this purpose. However, Alibag being a coastal station, magnetic recording are supposed to be influenced by the induced oceanic currents from Arabian Sea. Also, in the study of palaeomagnetism the ancient poles were all reduced to the latitude and longitude of a central place in the country. Nagpur is suitably located to fulfill both the conditions. University of Nagpur facilitated this, by extending suitable land in the University campus to establish a magnetic observatory. The Nagpur observatory became functional in the year 1991. .

Initially, fluxgate magnetometer was inside the variometer room where analogue variometer was also operational. Recently a separate underground vault has been constructed to avoid interaction between analogue and digital magnetometers and to achieve better temperature stability.
