a An image of a band-shaped aurora obtained by the NIRAC. It is mapped onto geographical coordinates at 110 km altitude. White dotted lines on the image are Altitude-Adjusted Corrected GeoMagnetic (AACGM) latitude and longitude (Shepherd 2014). A darkmagenta line indicates the FOV of the NIRAS-2, and darkmagenta circle, diamond, cross are the positions of the KHO, the NIRAS-2 data of interest in subsequent analyses, and the ESR beam. b A dark-subtracted image obtained by the NIRAS-2 when the band-shaped aurora appeared. Horizontal and Vertical axes correspond to wavelength and space (meridional), respectively
