Abstract: We investigate two active regions observed by the Hinode X-ray Telescope (XRT) and the Transition Region and Coronal Explorer (TRACE). One active region shows constant brightness in both XRT and TRACE observations. The other active region shows a brightening in the TRACE observation just after a decrease in X-ray brightness indicating the cooling of a coronal loop. The coronal magnetic topology is derived using a magnetic charge topology (MCT) model for these two active regions applied to magnetograms from the Michelson Doppler Imager (MDI) on board the Solar and Heliospheric Observatory (SOHO). We discuss the results of the MCT analysis with respect to the light curves for these two active regions.
