Measurement of solar EUV/UV radiation of the steeply rising solar cycle 22 during the San Marco 5 mission and proposed instrumentation to achieve high radiometric accuracy

Abstract

Aboard San Marco-5 the measurement of the solar and airglow radiations from 20 to 700 nm with one and the same instrument has been performed from March to December 1988 in an equatorial elliptical orbit. Preliminary results of solar spectra, flux changes and airglow emissions from different directions (zenith to nadir observations) are reported here. In this context, solar and airglow EUV/UV measurements from satellites are reviewed showing the lack on in-flight calibration. A rather small instrumental package compromising requirements from aeronomy, monetary resources available and present state technology is presented. - Other topics as being worked on in ASSI data evaluation are introduced.
