Scientific paper

Observations at Godhavn, Greenland, show that the intersection of the polar cleft with the ionosphere can be recognized by simultaneous occurrence of hydrogen emissions (H-alpha, H-beta) and enhanced O I 6300-A emission. The H-alpha line reveals a characteristic narrow and symmetric Doppler profile which is interpreted as indicating that the solar-wind protons retain their typical flux and energy spectrum all the way down to the ionosphere. The cleft intersection seems to cover the sector from 04:00 to 22:00 geomagnetic time.
