An evolutionary feature of the magnetic field related to flares in active regions

Wavelength coincidences are noted between laboratory and solar spectral line lists for the twenty-electron ions CaI, TiIII, CrV, MnVI, FeVII, and NiIX, which imply likely identifications for a large number of unidentified lines in the solar lists. These identifications should be useful, e.g., for improving chromospheric/coronal abundance estimates of the less abundant elements titanium, chromium, and manganese.
