Observations of 50-MHz type-II coherent echoes from within the polar cap
50-MHz type-II coherent echoes at geometrical aspect angles of 11.5° have been observed in the northern polar cap during pre-noon hours. The echoes had an unusually large Doppler width of 1200-1400 m s<sup>-1</sup> and were well correlated with strong magnetic disturbances in the rang...
