Non-Eckersley-law Whistlers observed at Equatorial Latitudes with Satellite Injun 3

THIS communication reports two new whistlers discovered in the very-low-frequency radio noise data from Injun 3 satellite. This satellite carried a very-low-frequency receiver with a magnetic loop antenna oriented so as to detect the component of the wave magnetic field which is propagating perpendicular to the geomagnetic field. The pass band of the very-low-frequency receiver was about 0.5–7 kc/s. Altitudes ranging from 237 km to 2,785 km are covered by the Injun 3 very-low-frequency data.
