Query: A High Resolution Mosaic of Molecular Gas in Stephan's Quintet   We present high resolution CO J=1-0 observations of the molecular gas in the
Hickson Compact Group Stephan's Quintet (HCG92). Our observations consist of
multiple pointing and mosaics covering all the regions where CO and star
formation has been detected. Within the 100'' field of view centered on the
eastern-most tidal tail, we detect three clumps of emission that may be
partially resolved at our resolution of 8''; two of these are new detections
not previously seen in ISM studies of this region. Two of these clumps lie in
the optical tidal tail, while the third lies to the southeast and is coincident
with a large HI feature, but does not correspond to any features at other
wavelengths. We also tentatively detect CO emission from the star forming
regions in the ``Old Tail'' corresponding to recent star formation activity
detected in recent UV and H$\alpha$ observations. Observations of the rest of
the compact group do not show detections even though strong emission was
detected with single dish telescopes, which suggests the CO emission originates
from a diffuse molecular gas cloud or from more at least three separate clumps
with separations of greater than around 3 kpc.
