We present far ultraviolet (FUV:1350 1750Ang) spectral imaging observations recorded with the SPEAR satellite originating in a 60° x 30° rectangular region close to the North Galactic Pole. We have obtained maps of interstellar emission line intensity including the lines of CIV (1550Ang), SiIV (1394Ang) and SiII* (1533Ang), binned to a spatial resolution of 4 sq. deg. on the sky. These data represent the first spectral maps of the of the highly ionized medium (HIM) and the warm ionized medium (WIM) recorded at high galactic latitudes. The data are presented as line intensity ratio maps, e.g. CIV/SiIV and CIV/SiII*, such that the observed spatial variations in these ratios can be associated with the varying physical conditions of interstellar gas at high galactic latitude.
The SPEAR (or “FIMS”) is supported by NASA grant NAG5-5355 and flies on the STSAT-1 Mission, supported of the Korea Ministry of Science and Technology.
