The analysis of the high-resolution UVES spectra of the chemically peculiar stars HR6000 and 46 Aql has revealed the presence of an impressive number of unidentified lines, mostly concentrated in the regions 4404-4411 Å and 5100-5300 Å. Almost all of the unidentified lines are the same in both stars, which both have an iron abundance enhancement of the order of +0.7 dex over the solar value. The parameters adopted for HR 6000 and 46 Aql are Teff=12850 K, log g=4.1 and Teff=12750 K, log g=3.8, respectively. We show that some of the unknown lines can be identified as high-excitation (lower EP13eV) FeII and that most of them appear as unclassified lines in laboratory iron spectra.
