New identifications of Fe XVII spectral lines in solar flares

We review the identifications of Fe XVII transitions between the |2s²2p⁵3s,3p|⁠, and 3d configurations recently published by Jupén. Our review is based on examining spectroheliograms of solar flares obtained by a Naval Research Laboratory instrument on Skylab (S082-A). We agree with the majority of identifications given by Jupén, but find different wavelengths for a few of the lines. The relative intensities of the lines are qualitatively in agreement with calculations. We also identify a broad line at 1153.20 Å with the |2p⁵3s³P₀→ 2p⁵ 3s ³P₁| forbidden transition of Fe XVII. This line was found in flare spectra obtained by the NRL slit spectrograph on Skylab (S082-B).
