    The G supergiant $\beta$ Dra is one ofthe most coronally-active, low-
    gravity cool stars. It has a high temperature ($log T \approx 7.2$)
    corona that must be magnetically confined to the star.We propose the
    first detailed study of the temperature and emission measure distrib-
    utions for the corona of a G supergiant, using spectra from a 30ksec
    ASCA observation of $\beta$ Dra. Models of the coronal and transition
    region structure will be calculated.  The coronal energy budget will
    be estimated and constraints placed on the coronal magnetic field.
    Because G supergiants have outer atmospheres that evolve very rapidly
    , they provide important information pertinent to the whole question
    of the processes leading to the formation of stellar chromospheres
   and coronae.
