Scientific paper

We present the results of far-ultraviolet (FUV) observations of comet C/2001 Q4 (NEAT) obtained with Far-ultraviolet Imaging Spectrograph (FIMS) on board the Korean microsatellite STSAT-1, which operated at an altitude of 700 km in a sun-synchronous orbit. FIMS is a dual channel imaging spectrograph (S-channel 900-1150 Å, L-channel 1350-1750 Å, λ/Δλ ~ 550) with large image fields of view (S: 4°.0×4'.6, L: 7°.5×4'.3, angular resolution 5'-10') optimized for the observation of diffuse emission of astrophysical radiation. Comet C/2001 Q4 (NEAT) was observed with a scanning survey mode when it was located around the perihelion between 8 and 15 May 2004. Several important emission lines were detected including S I (1425, 1474 Å), C I (1561, 1657 Å) and several emission lines of CO A1π-X1Σ+ system in the L-channel. Production rates of the notable molecules, such as C I, S I and CO, were estimated from the photon fluxes of these spectral lines and compared with previous observations. We obtained L-channel image which have map size 5°×5°. The image was constructed for the wavelength band of L-channel (1350 - 1710 Å). We also present the radial profiles of S I, C I, CO obtained from the spectral images of the central coma.
