THE intensities of 10 keV and 4 keV electrons have been measured from a sounding rocket launched into a post-breakup aurora. Pulsations in electron intensity were observed with a period of about 4 sec at both energies. The 10 keV pulsations occurred about half a second earlier than those at 4 keV. These results could have been caused by temporal changes in electron intensity and by a spatial structure in the path of the rocket because the causes are indistinguishable in the data. We treat the… Expand
