Soft X-ray observations of a filament located near NOAA AR 4640 were obtained with the Flat Crystal Spectrometer (FCS) on board the Solar Maximum Mission satellite on April 3-12, 1985. On April 7 the filament partially lifted off. At the same time and location an enhancement was imaged in soft X-rays. A total of 16 h of FCS observations, including 25 raster images, were made of the filament prior to the eruption, and over 40 h of observations, including 57 raster images, were made following the eruption. Careful alignment of H-alpha images taken during the same period has made possible the calculation of the integrated soft X-ray emission around the filament channel before, during, and after the eruption. Kitt Peak magnetograms have also been examined for this period to determine the corresponding magnetic field structure. A time history of the eruption in X-ray and optical wavelengths, and the development of the magnetic-field structure are presented. Evidence is seen for X-ray brightening in preexisting magnetic-field loops over the filament.
