متن کاملInterplanetary Magnetic Field Structures out of the Ecliptic
New observations of the out-of-the ecliptic trajectories of type III solar radio bursts have been obtained from simultaneous direction finding measurements on two independent satellite experiments, IMP-6 with spin plane in the ecliptic, and RAE-2 with spin plane normal to the ecliptic. Burst exciter trajectories were observed which originated at the active region and then crossed the ecliptic p...
متن کاملDENSITY AND MAGNETIC FIELD SIGNATURES OF INTERPLANETARY 1/f NOISE
We investigate the occurrence of noise in the interplanetary density and the magnetic field at varying heliocentric 1/f latitudes. The characteristic spectral amplitudes can be found in Ulysses density and magnetic data in the expected frequency ranges at all available latitudes, ranging from the ecliptic plane to more than 80 . Average spectra indicate a latitudinal variation, with a density s...
متن کاملSolar Wind and Interplanetary Magnetic Field: A Tutorial
The convection layer completes the transport of energy from the nuclear furnace at the center of the sun to its radiation into space by the photosphere, but most importantly for the solar wind it sets the temporal and spatial scales for the structure of the coronal magnetic field that in turn controls the properties of the solar wind. In this tutorial review we examine the properties of the fie...
متن کاملModulation of dayside reconnection during northward interplanetary magnetic field
[1] On 17 September 2000 the IMF was directed continuously northward for more than 3 hours. Density fluctuations in the solar wind resulted in quasiperiodic variations in the solar wind dynamic pressure, and correlated fluctuations also occurred in the IMF Bz component. The Northern Hemisphere SuperDARN radars observed bursts of highlatitude high-velocity plasma flow during this northward IMF i...
