Volume : III, Issue : VII, August - 2013 Notation And Classification Of Geomagneticmicro Pulsation Hanumantha Raju N DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : A electromagnetic micro pulsation recording system, consisting of a core coil, input filter, shaping filter,
recorder and a statistical analog computer is described. A major consideration in the design of the system is that it be
duplicable with a minimum of available technical facilities. The present system of classification of geomagnetic
micro pulsations is rather arbitrary based mainly on the morphological features observed in the records. A better
method would be to base the classification on some physical parameters connected with their generation and
propagation. An attractive possibility is seen in the measurements by satellites of the interplanetary magnetic field
and magnetospheric quantities. Using interplanetary magnetic field parameters recorded aboard Explorer 28, an
attempt is made to find a relation between these parameters and the geomagnetic micro pulsations of 120 to 20 sec
periods (30-180 cph) observed in the Telluric current activity recorded in Alaska. It is found that pulsations in the
range 30-120 cph behave in a different manner compared to the pulsations in the range 130-180 cph. Keywords : Article : Cite This Article : Hanumantha Raju N, (2013).
