Abstract This paper deals with the initial observational data on the field-aligned currents (FAC) and the small-scale transverse magnetic perturbations (SSTMD) in the cusp region obtained from the magnetometer on board the Intercosmos Bulgaria-1300 satellite. The magnetic field has been investigated by a high accuracy flux-gate magnetometer, IMAP, designed in the Central Laboratory for Space Research (CLSR), Sofia. For low geomagnetic activity 10 meridional passes (September–December 1981) have been examined. Intense FAC are observed in the noon sector of the summer auroral region. SSTMD are superimposed on a weak cusp current as a perturbation in the prenoon sector of the winter auroral region.
