Five of the extreme ultraviolet channels (L&agr;, L&bgr;, He I, He II, Fe XV) measuring irradiance fluctuations on board the AE-E satellite between 1977 and 1980 have been studied in detail. It is shown that the daily variations correspond very closely to the daily variations in solar radio emission (F10.7), but that the UV data are afflicted with serious and to dat unrecognize calibration changes during the period of operation of the instruments. In order to correct for these changes, a statistical analysis is carried out, and a set of corrections to the raw data is suggested. We then compare the resulting, now uniform, data with rocket measurement (L&agr;) and data acquired onboard the AE-C satellite (L&bgr;). Finally, we discuss the remaining discrepancies. After concluding that they are below the overall level of uncertainities, we propose a first-order 10-year run of EUV irradiances derived from F10.7 data. This estimate includes the ratio of irradiance levels between the maxima of solar cycles 20 and 21 and the intervening minimum.
