The Electron Solar Probe Analyzer (SPAN-E) instruments are a matching pair of opposing electrostatic analyzer instruments that are a part of the Solar Wind Electrons Alphas and Protons (SWEAP) instrument suite on Parker Solar Probe (PSP). The SPAN-E instruments can measure electrons with energy between 5 eV and 30,000 eV in over 90% of the full sky. The SPAN-E instruments were launched from Florida in August of 2018 and a modicum of data from commissioning has just been returned. This presentation will show the details of the instrument operation and planned observation modes that are possible during the first Parker Solar Probe near-sun encounter, as well as show some of the initial electron data returned from spacecraft commissioning.
