Hot Non-Potential Core in AR 11433

The movie above shows XRT observations of NOAA Active Region 11433 in Ti-poly filter starting from 12:20 UT on 2012 March 16. A highly sheared structure constantly brightens up in the core of the active region. A more elongated and highly sheared structure becomes visible around 14:00 UT. The elongated structure then rises up, which is associated with the appearance of more brightening sheared loops in the core of the active region. These sheared structures are hot because they are only visible in the hotter SDO/AIA channels (e.g., 94 and 335 Angstroms).
