Oi. Prokopenko et Aa. Nusinov, Determination of the ultraviolet emission flux from solar flares on the basis of the disturbances in the ionospheric E-layer, GEOMAG AERO, 41(1), 2001, pp. 109-113
An estimate of the increments in the absolute values of the extreme ultravi
olet emission (shorter than 105 nm) from solar flares is obtained. A compar
ison between the absolute values of the solar ultraviolet emission flux fro
m direct satellite-borne measurements and the results of a calculation of t
his flux, carried out on the basis of critical frequencies measurements in
the daytime midlatitude E layer during flares, is performed. It was shown t
hat the calculated ultraviolet emission fluxes are similar to the fluxes me
asured from satellites.
