摘要: Abstract The intensities of auroral electrons with energies 10, 4 and >2 keV have been measured from a rocket launched into post-breakup aurora Andoya in Northern Norway. Changes intensity periods greater than one second are found to occur earlier at 10 the other energies; average delay between is 0.45 ± 0.1 sec 0.18 0.06 sec. delays interpreted as dispersion effects following modulation or near geomagnetic equator on L = 6 magnetic shell.
