Scientific paper

The first results of the Solar Lyman (Solly) observations, are presented. The Solly payload was launched on October 24, 1988, and reached an apogee of about 350 km. The experiment Solly consists of a hydrogen cell containing molecular hydrogen at low pressure and is sealed by magnesium fluoride windows. A hot filament dissociates the molecules into hydrogen atoms. By measuring the scattered Ly-alpha photons with a sideways mounted detector, the core region of the solar Ly-alpha line can be studied. Another detector is positioned along the optic axis at the rear of the instrument and measures the total intensity of the solar photons near 1216 angstroms.
