Data on solar emission variations in the extreme ultraviolet range lam
bda<1300 angstrom (EUV-range) performed on board the ''Prognoz'' satel
lites and the ''Phobos'' spacecraft by the thermoluminescent method ar
e presented. Flux variations from the 11-years cycle are factors of 2-
2.5, and that by the 27-days cycle do not exceed 30%.
