We present a map of molecular hydrogen in the Galaxy observed from its far-ultraviolet fluorescent emission. The map was obtained using observations over most of the sky using the SPEAR (FIMS) instrument, aboard the STSAT-1 satellite. Fluorescence emission is one of the few available direct tracers of molecular hydrogen. While the molecular hydrogen is concentrated toward the galactic plane, it is not strictly limited to low galactic latitudes. The coverage and quality of our data should allow us to place constraints on the column and destruction rate of Galactic interstellar molecular hydrogen and to compare its distribution with interstellar atomic hydrogen and dust over a variety of environments.
The SPEAR (FIMS) is supported by NASA grant NAG5-5355 and flies on the STSAT-1 Mission, supported of the Korea Ministry of Science and Technology.
