STSAT-1, also known as KAISTSAT-4, has been in operation more than a year since its launch on September 26, 2003. While the
primary objective of the mission is to provide spectral information of diffuse hot Galactic plasmas and supernova remnants
with Far Ultra-violet Imaging Spectrograph (FIMS, also known as SPEAR), the same instrument also makes observations of
auroras and airglow with high spatial resolution and detailed spectral information for a space physics mission. The FIMS
bandwidth, 900 - 1175 A and 1335 - 1750 A, includes important oxygen and nitrogen lines such as OI 989 A, N+ 1085 A, N I 1134
A and 1493 A, as well as Lyman-Birge-Hopfield (LBH) emissions. Over the polar region, FIMS spectral image is compared with
simultaneous in-situ measurements of keV electrons on the same spacecraft. FIMS observes auroras regularly twice a day and
airglow occasionally. Especially, FIMS made limb scanning on several occasions in the dayside using its short band (900 -
1175 A). We will discuss the height profile of atomic oxygen and nitrogen obtained from this set of observations. We will
also compare the results with those of AURIC simulations.
