Le satellite S.M.M. (Solar Maximum Mission). Un observatoire tout entier consacré à l'activité solaire.
Abstract
The instrumentation on-board the SMM is described, together with data gathered up to November 1980. The SMM carries a gamma ray spectrometer, two hard X ray spectrometers, an X ray polychromator, an UV spectrometer polarimeter, a coronograph/polarimeter and a radiometer. The observational data linked the eruption processes with the appearance of parasitic magnetism, the disappearance of a filament, plasma temperature enhancement to 50,000 K, an increase in the 6 cm flux continuum and hard X ray emission. Measurements have confirmed a two-stage flux acceleration, with highest temperatures happening before peak emissions. The deeper understanding of solar flux phenomena gained with the SMM has been due in large part to an internationally cooperative effort to confirm space-based observations with ground-based measurements.
