CDS rasters (O V 629.39 Å line) of the source flare in event 2 between 10:29:15 and 10:56:31 UT on 2002 August 19. Times are given for the beginning of the rastering. Top row: intensity (photons s⁻¹ cm⁻² sr⁻¹). Middle row: wavelength shift relative to the median wavelength taken from the full image. Bottom row: FWHM of the line. The contours for every 0.25 of log₁₀ intensity are overplotted.
