In the press conference held on 20 December 2006, latest data and movie from X-Ray Telescope (XRT) had been released. XRT observes corona of million degrees. It is still a mystery how the corona is heated to that high temperature. This movie show activity of solar corona for 12 days. An active region goes behind the west limb while another one comes from east limb. Ubiquitous small brightenings suggest magnetic activity is taking place all around the Sun.
