H I Br α (4.05 μm), [Ne II] (12.8 μm), and [Ar III] (9.0 μm) emission lines from Sgr A West were mapped with ~100 km/s and 2″ resolution. The observations were made with the U. T. infrared echelle spectrometer (IRSHELL) on the IRTF in April 1988. The instrument simultaneously measures 10 64-point spectra along a 2 × 10″ slit. Data analysis is still in progress; preliminary results are presented here.
