A geomagnetic sudden commencement (SC) was observed by the low altitude geomagnetic satellite, MAGSAT, when it was flying very closely above a ground station (Magadan in east Siberia, geomagnetic latitude=51.1°) in a duskside (16-17h LT) meridian. The H-component at the satellite showed a positive p...
