An extensive data base on high-latitude waves will result from the ten months' operating period of the Viking satellite, during which the high frequency wave experiment, V4H, has worked continuously. Preliminary analysis of a small fraction of these data has given results concerning auroral kilometric radiation (AKR) as well as lower-frequency waves. The findings are as follows: (1) AKR waves exist in both R-X and L-O mode, R-X mode being strongest; (2) the frequency range of AKR is from about 100 kHz to at least 500 kHz; (3) the R-X mode propagates upwards in a cone or conical shell filling less than a half sphere; (4) AKR is generated in a narrow latitudinal range within the auroral oval, in the evening sector, and at altitudes of several thousand kilometers; (5) AKR is electromagnetic at the source and no strong electrostatic mode is observed; and (6) there is fine structure in AKR, as well as a continuous spectrum. Below the cyclotron frequency, auroral hiss, limited upwards by the plasma frequency, as well as Z-mode radiation has been observed, and, in the polar cap, electrostatic bursts of a few seconds duration are frequently observed.
