Abstract (2. Language): 
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.
