Auroal hiss is rarely seen at sub-auroral-zone ground stations, but during the 4-month period January--April 1976 it became very prevalent in the wide-band, audio frequency, synoptic whistler records at Farewell. Alaska (L=4.2). A possible reason for this is that in the normal reduction and retreat of auroral zone effects to higher latitudes at sunspot minimum the reduction in the particle precipitation which causes auroral absorption is greater than that in the softer precipitation which causes auroral hiss. The occurrence of auroral hiss at Farewell showed, at 21 hours LMT (local magnetic time), the same strong diurnal peak found at auroral one and polar cap stations. The low-frequency cutoff of auroral hiss on the ground is also discussed.
