  The Cygnus Superbubble (CSB) is a region of soft X-ray emission approximately
13 degrees wide in the direction of the local spiral arm. Such a large region
might be the result of strong stellar winds and supernovae from nearby stellar
nurseries, or it could be the result of a single event - a hypernova. HaloSat
observed 4 non-overlapping 10 degree diameter fields in the CSB region over the
0.4-7 keV band. The CSB absorption and temperature was found to be consistent
over all 4 fields, with a weighted average of 6.1x10^21 cm^-2 and 0.190 keV,
respectively. These observations suggest that the CSB is a cohesive object with
a singular origin. The total thermal energy for the CSB is estimated at 4x10^52
erg, based upon a shell-like physical model of the CSB. Absorption and distance
estimates to Cyg OB associations are examined. The CSB absorption is found to
be most consistent with the absorption seen in Cyg OB1, implying that the CSB
lies at a similar distance of 1.1-1.4 kpc.
