Abstract : Measurements of the transverse scale of F-layer irregularities, based on radio-star observations from College, Alaska, at frequencies of 68 and 223 MHz, are reported. Analysis by the two-frequency scintillation-ratio technique yields typical scales of 600 to 700 meters for mid-auroral latitudes. Typical scales of one kilometer are found for higher-latitude irregularities. The latter show increasing scale with increasing magnetic index. Analysis by the two-frequency correlation technique produces erroneously small scales due to refraction effects. (Author)
