Since its launch, the Alpha Magnetic Spectrometer - 02 (AMS-02) has deliveredoutstanding quality measurements of the spectra of cosmic-ray (CR) species,$\bar{p}$, $e^{\pm}$, and nuclei, $_1$H-$_8$O, $_{10}$Ne, $_{12}$Mg, $_{14}$Si,which resulted in a number of breakthroughs. One of the latest long awaitedsurprises is the spectrum of $_{26}$Fe just published by AMS-02. Because of thelarge fragmentation cross section and large ionization energy losses, most ofCR iron at low energies is local, and may harbor some features associated withrelatively recent supernova (SN) activity in the solar neighborhood. Ouranalysis of new iron spectrum together with Voyager 1 and ACE-CRIS data revealsan unexpected bump in the iron spectrum and in the Fe/He, Fe/O, and Fe/Siratios at 1-2 GV, while a similar feature in the spectra of He, O, Si, and intheir ratios is absent, hinting at a local source of low-energy CRs. The foundexcess fits well with recent discoveries of radioactive $^{60}$Fe deposits interrestrial and lunar samples, and in CRs. We provide an updated localinterstellar spectrum (LIS) of iron in the energy range from 1 MeVnucleon$^{-1}$ to $\sim$10 TeV nucleon$^{-1}$. Our calculations employ theGalProp-HelMod framework that is proved to be a reliable tool in deriving theLIS of CR $\bar{p}$, $e^{-}$, and nuclei $Z\le28$.
