Brief Description (Abstract):

It is observed that the just sub-auroral Indian Antarctic station Maitri is very sensitive to the electromagnetic changes in the geo environment. Observations of the three components of the geomagnetic field X, Y, Z and the 30 MHz cosmic radio noise signal recorded by Riometer (RIO) at Maitri can provide clues to the state of Space Weather, and for that matter the state of Interplanetary space. Maitri data of X, Y, Z and RIO during Jan-Feb 1999 are used to highlight this aspect.

Status: Completed

Purpose: ?Geospace Weather? can be defined as the electromagnetic state of the Earths space environment. This encompasses the electric and magnetic fields, the particle populations and their distributions in the entire ionosphere-magnetosphere system. The Earliest recognition of Space Weather can be traced back amongst others to Gilbert (1600) for realising that the Earths magnetic field extends into space all around in 3 dimensional form, Graham (1724) and Celsius (and Hiorter) (1741) for noticing oscillations in compass needles and in ammeters during auroral displays and de Marian (1754) for postulating that auroral and geomagnetic storms are caused by the entry of charged particles of solar origin into the geo environment.
