High frequency waves in two frequency bands above the electron gyro frequency (1.6 MHz and 2.3 MHz) were observed by radio receivers carried on a sounding rocket as it passed over a strong aurora. Only the line at 2.3 MHz has a large magnetic component. Both 0.4s and 4s periods are present in much of the emissions. Good correlation is seen for a short time between the 2.3 MHz waves and 1.9 keV electrons detected on board the rocket.
