Wideband VLF electromagnetic bursts are observed on the DE 1 satellite by both the electric and magnetic field sensors in the frequency range of 0.650 kHz to 16.0 kHz. The impulsive signals endure for a relatively short time ({approximately}1s or less) and exist in the frequency range from well below to well above the local gyrofrequency. They are typically found at L > 4 over a {approximately} 40{degree} range of latitudes including the geomagnetic equator and are often accompanied by discrete emissions or a band of hiss. Some observed features are consistent with previous observations of electrostatic plasma waves (Ondoh et al., 1989; Reinleitner et al., 1983); however, the magnetic measurements clearly indicate that the impulsive signals are electromagnetic in nature, a result that has not been reported before. The possibility of spacecraft discharge effects as the cause of these signals is discussed.
