Abstract
We have used the S-056 X-ray data from Skylab to determine quantitative values for the coronal conditions characterizing a new bipolar magnetic region (BMR). In particular, we include: (a) the time variation of the total soft X-ray flux from the BMR as a function of time; (b) the temporal and spatial variation of the temperature and emission measure; (c) the variation with time of thermal energy density; (d) the (calculated) magnetic field configuration and magnetic flux density in the corona; and (e) the temporal variation of the magnetic field energy in the corona. Detailed comparisons are made between the configuration of X-ray features and the magnetic field topology.
