Abstract
DURING the auroral display of January 24, short pulses of radiation were observed on the indicator of a radar set operating at a frequency of 3,000 megacycles. Since these pulses were observed even when the radar transmitter was off, it seemed probable that they were associated with the auroral display. Observations on twenty auroral displays since January 24 seem to confirm the auroral origin of these pulses.
