Paper Abstract

The rocket and then the satellite investigations of the solar ionizing flux were started nearly fifty years ago (1946) but they still have not led to the permanent monitoring of the soft x ray and EUV solar radiations -- the principal factor that is controlling the main processes and parameters of the ionosphere and upper atmosphere and the energetics of solar-terrestrial relation. In view of this important fact and taking into account the EUV and particularly x ray variability which differs strongly for each of the solar rotations and solar cycles especially during solar flares, our knowledge of these fluxes is astonishingly incomplete. The main reason of the absence of the permanent solar radiation patrol is exclusively connected with technical and methodological difficulties of the space measurements in this spectral range. The present paper proposes a possible way of deciding the problem using the experience of the S.I. Vavilov State Optical Institute in the measurements of the solar ionizing fluxes on the satellites Cosmos-262 and Cosmos-381. The optical apparatus for the space permanent patrol are briefly described and some methodological problems of the information processing are discussed taking into account the real space conditions under which the registration of the EUV and x- ray fluxes is carried out.
