The Soft X-ray Telescope (SXT), on the Japanese solar satellite Yohkoh, with its high time (up to ms) and spatial resolution (up tp 2.5''), obtains images of the Sun in sufficient detail to enable us to study fast time changes and energy release processes in flares and active regions. Here we present SXT observations of several active regions obtained from February through April 1992. These images show a variety of morphological changes in the active region loop structures and their interaction within a time interval of 10 to 20 minutes. In particular, we will show examples of dramatic topological changes in the active regions accompanied by the reconfiguration of loop structures and brightness variations. These examples provide clear evidence of loop interaction and can be best interpreted as being due to magnetic reconnection. Implications of observations on coronal heating mechanisms will be discussed.
