Scientific paper

An imaging echelle spectrograph designed for high resolution studies of selected spectral features located anywhere in the visible was deployed during November 2001 to March 2002 in Tromso, Norway. The purpose of the experiment was to assess the particle precipitation characteristics and the subsequent response of the ionosphere, in a region of intense proton aurora. For moderately distrubed conditions, Tromo is located for several hours on the equator edge of the evening auroral oval, where energetic protons are the dominant particle energy source. It also offers combined experiments with the EISCAT radar probing the ionosphere. Four spectral windows were selected in this study: Hα (656.3 nm) and Hβ (486.1 nm), N2+ 427.8 nm and OI 777.4 nm. The 8° long slit of HiTIES (High Throughput Imaging Echelle Spectrograph) was centered on the magnetic zenith. Information on the weather conditions and on the overall auroral activity is provided by a second spectrometer, the Proton Aurora Context (PAC) instrument. PAC is a large field of view (60°) conventional imaging spectrograph which spans the 400-800 nm spectral range. Both optical instruments operated over the whole winter. In this talk, we demonstrate that the spectral resolution of HiTIES (~ 0.1 nm) is sufficient for successfully studying proton aurora using Hα emission. The same experiment will be repeated this winter.
