SuperTIGER (Trans-Iron Galactic Element Recorder) is a large-area balloon-borne instrument built to measure the galactic cosmic-ray abundances of elements from Z=10 (Ne) through Z=56 (Ba) at energies from 0.8 to ~10 GeV/nuc. SuperTIGER successfully flew around Antarctica for a record-breaking 55 days, from December 8, 2012 to February 1, 2013. In this paper, we present results of an analysis of the data taken during the flight for elements from Z=10 (Ne) to Z=28 (Ni). We report excellent charge separation throughout this range, with an Fe charge resolution of 0.16. We will compare our galactic element abundance measurements, secondary to primary ratios (e.g. (Si+Ti+V)/Fe), and energy spectra with those from other instruments operating at different energy ranges.
