The first observations of the signatures of Pc1 pulsations in ionosonde echo data are reported. Oscillations are frequently observed in Doppler velocity, echo amplitude, group range and skymap echo-location position, and are clearly associated with simultaneous Pc1 geomagnetic micropulsations with a similar frequency. These oscillations, recorded at the sub-auroral Antarctic station of Halley (76° S, 27°W, L ~ 4.2), occur in either or both E- and F-region echo time series during a wide range of ionospheric conditions. Focusing of the ionospheric echoes due to the compressional action of the hydromagnetic wave is suggested as a possible mechanism.
