We report observations of magnetic fields in Giant Molecular Clouds (GMCs), obtained using the technique of submillimeter polarimetry. We used a polarimeter called SPARO [1, 2] that we built at Northwestern U. and that we use together with a 2-meter telescope at South Pole station. In comparison with submillimeter polarimeters that have been operated from larger telescopes on Mauna Kea, SPARO obtains relatively coarse angular resolution but much better sensitivity to fainter, more extended emission. We have also discussed these recent SPARO observations in a paper in the Astrophysical Journal [3].
