Comparison of SW spectra of β Cet from flare segments of the year 2000 observation (dark shading), low‐activity segments of the same pointing (medium shading), and the 1994 September observation (light shading). The spectra were smoothed with a 0.4 Å FWHM Gaussian (the intrinsic SW resolution is ~0.5 Å). Dot‐dashed curves depict ±1 σ photometric uncertainties for the 1994 spectrum. Noise levels in the new observations are similar. Note compressed flux density scale of bottom panel. Numerals identify prominent coronal iron lines (e.g., ﹩20=\mathrm{Fe}\,﹩ XX).
