Spectrographic Imaging Facility (SIF)


The University of Southampton/University College London (UCL)

Scientific objectives
To study proton and electron precipitation using spectrographic measurements at high spectral resolution. The spatial and temporal changes in small scale structures within the aurora are also a subject that is addressed with the combination of spectrograph, four photometers and a narrow angle camera.
